I've Seen that some of you guys have warmed up your 235's, with intakes, headers, carbs, ect. I have a 57 9 passenger wagon that has 0 Lbs compression on #1 90 Lbs on #2 120 LBS on #3 #4 90 Lbs on #5 #6 Debating on rebuilding or replacing with V8? Is it possible to to get a "lumpy bump stick" to make it a little meaner sounding? What all can you do to a 235? Thanks for your input.

I had a six cylinder in a car before and was at the same point your are at. I wanted to go faster and louder, I was 18. What I learned was, if you think you really want a V8 then ditch the 6 now. Do not start putting money into something you wish was a V8. The happiest day for me was when my 6 threw a rod and it gave me an excuse to finally get a V8. I was much happier. If you really want to keep your 6 there are many things you can do to go faster,

You should ask this questsion in the 42-54 forum as those are all 6's and some of those guys have done quite a pit to theirs. I don't know the numbers, but I have heard that done right, they can put many small v8's to shame. I just put Fendton headers and dual exhaust on my 57 235, and I just picked up a Fenton dual carb intake that I will be putting on soon. I still have the original cam, so I won't get all the benefit of these up grades, but it sure will help. Besides, how often do you see a hot rodded 6? If you want to be different and cool, rebuild your 6. I'll warn you though, it will cost more than a SBC, but probably not if you have to buy the V8 first.

Also, be sure you find a machinist that knows these old engines. I just went through that with mine. They didn't make the clearences on the valve guides large enough and I ended up with a stuck valve and a bent push rod. See my post in the stock forum. http://www.chevytalk.org/fusionbb/showtopic.php?ti...

I forget if it was at Indy or Louisville, but there was a 57 with a 6 that had a blower on it with all the other stuff. It was about 10 years ago that we seen it.

In the mid-sixties I had a buddy who was running a beautiful '51 Chevy hardtop with a '62 GMC 292 ci truck block in it. The 292 was a tall deck six, and his had been reworked to 300 ci, with ported heads, 3 side draft carbs, headers/dual exhaust with cutouts, and a 4 speed/floor shifter. The rear end I think came out of an oldsmobile. He routinely cleaned the v8 chevies who came up against him. And it sounded nasty, as he had smitty's on it, which gave a nice mellow rumble while cruzing thru town but had a wicked rapp when we got out in the country rowing through the gears!

They are worthwhile projects, and I've seen 'em with blowers on 'em too, but they are not a cheap build, and for the money a v8 makes much more power. A properly built up and solid running six just has a lot of pizzazz factor that is hard to beat IMO......

I haven't done one for many years, but have a stock 235 in the shed now that I pulled out of my '55 4dr, complete with the original 3sp, that I need to do something with eventually. But if I were you, I'd park the 235 and look for a 292 ci, they were in Chevy and GMC trucks from 1962 to 1990, they had stout bottom ends, and there were plenty of them around.

There's a pretty good history of the Chevy six's on wikipedia (link) that's worth a read....

Good luck with it.
Aloha,
Willy

Years ago I had a 1954 Chevy pickup with a 235 six. It ran good and was dependable, but there was nothing exciting about it. If you just want a heavy lump of iron that will get you from point A to point B the 235 will get the job done.

If you are looking for an engine that is lighter, faster, and sounds mean a V8 is the way to go. You should be able to put together a healthy small block V8 cheaper than fixing the old 235.

Welcome to CT first classic!

Sixes respond to all the tricks applied to the V-8s, and the results are even more dramatic, as all suffer from poor breathing, with two exceptions - MoPar's Slant Six and the Pontiac OHC 250.

So much depends on what your vision is for the car and your budget, and how much work you are willing to do yourself to save a few bucks. If you are willing to sacrifice power for cool, keeping the 235 and warming it up would be the easist, with minimal changes to the car. For brute power for dollars spent, a streetable six will never match an equally prepared 350 - THERE IS NO REPLACEMENT FOR DISPLACEMENT! BUT - much of the money saved in building a SBC will be spent in upgrades to the car to make the install look sano and keep things reliable. What shape is the driveline in? Stick or auto?

A lumpy cam in a lil' 235 to move a heavy wagon around would really be the WRONG way to go - you'll need lower gears with a stick or a higher stall speed converter with an auto. to prevent "creep" while the car is in gear at a stoplight. A mild 3/4 or RV grind would boost both TORQUE AND POWER and is a vast improvement over the lame stock cam, with good vacuum available for a power brake booster.

Sealed Power still has good parts coverage of the 235, with better prices than Egge Machine. Compare local prices with the mail-order shops like Speed-O-Motive and P.A.W. Also check out Patrick's Antique Auto for parts and speed equipment.

Tech info can be had on Inliners International, Clifford Performance websites or from Tom Langdon at Stovebolt Engine Co. Both Clifford and Stovebolt have catalogs available.

A cool book to look for is the "Chevrolet Inline Six-Cylinder POWER MANUAL" by Leo Santucci. Though it covers the late 250/292 engine family, there is good info about planning the project and loads of cool photos - including the cover!

Hope we can talk again about Chevy sixes... PM's are always welcome!

Best Wishes, Tim

Thank you for the input. I think I like the idea of a hopped up 235. just for the fact that most every 55 56 57 I see has a V8. I think it would maybe draw some more attention at the hamburger stand if you know what I mean. I'm sure it would at least start a few conversations. I am willing and able to do the work myself, just didn't know if parts were still available or where to look. The car is 15 years older than I am and my father has never turned a wrench so he is no help. Tim THANK YOU for all the tips and leads. By the way you asked about the trans, gears. It Is a 3 speed, with stock gears. The P/O converted the 3 on the tree to a floor shift. Witch leads to my next question. What would I need to mount up a munci 4 speed?
Thanks Again for your replys

You will never get any real performance out of the 235, the head design is the main cuprit. As for looks and nastalga you can park a $1500 55 with a tricked out inline 6 next to $15000 55 with a samll block V8 and everyone will be looking under your hood and that tricked out 55 owner will be getting upset. 235 intakes are I believe limited other than stock to 2 or 3 barrel design. Camshafts are also limited but you can have yours reground. If your thinking of keeping a 6 as noted above the 292 does put out some really good tourque where as the 250ci can actually rev higher and cost less to build along with it is much easier to find. Top HP out of the 235 would probally be about 125 vs a 250 would have very little issues hitting 175+ and the availabilty of parts is certainly better and probally cheaper. Turbos are also avaialable for the 250/292 motors which can certainly up the hp numbers.

Don -- I can't say for sure what I would do in your situation, but the guys above make good points. At car shows, I walk from car to car with small blocks, pause for a while to look at a big block installation, but always stop and examine a well done six with cast aluminum goodies, multiple carbs, and headers or split manifolds. It's kinda cool to have something different.

Here is my 235. It is a solid lifter 1957 truck motor to go into my 1951 1/2 ton. It has a Holley 480 4 bbl carb on a Clifford manifold with water heat. It has a ceramic coated Fenton split exhaust header. It has an Iskenderian Cam and a converted GM electronic ignition. The balancer is for a 250 with 2 grooves cut into it so maybe I can install a/c. For my truck it has a plate to mount an earlier water pump. It centers the fan better and the pump has a shorter nose than the 57 pump, so it will fit in my earlier truck.

I am sure there is a crowd that likes looking at the multiple carbs, but I would rather put a fuel injection system on this. Maybe someday, once I get it together and running this way.

I still need to work out the carb linkage and whether I will have the a/c pump and or power steering. Of course I need to work on the truck to put it in as well.

Why not use a set of triple DCOE Weber carbs ?
The big european 6 cyl use them often. Looks nice, makes good power and sounds awesome


for example.
The manifold will be a challenge though.

Todd -- nice motor, man. I didn't mean to exclude 4-bbls in my post above.

What kind of TQ and HP do you expect it to make? Someone above commented that you couldn't expect much more than 125HP out of a 235. That sounds kinda low to me.

Maybe a little low? My Jeep has the 4.0 HO 6, it's overhead valve, cam in block, slightly larger displacement (about 30 ci?), y-exhaust manifold. The big difference is electronic ignition with coil packs instead of a traditional distributor, and throttle body injection. Chrysler rates it at 190hp, and I can attest that it does run pretty good if you're willing to rev it past 2500 rpm, it really pulls.

Couldn't a Chevy six get into this HP range? Or does the head flow prevent it?

Great looking mill Todd!

Did you mill the head to bump the compression up?
Any head work on the intake ports?
What are the specs on the Isky cam?

Have you given any thought to putting it on a dyno? I'm sure it would do better than 125 HP with the 4-bbl! HOT ROD DELUX featured a 235 build back in the summer of '08. Their motor dynoed at 125, with dual Rochesters on a Offy manifold and Isky 264 duration cam, no head work (I think). I was shocked and bummed that it was so far below the factory rating of 140 - with just a 1-bbl. I know most factory ratings are optimistic, no two dynos will read the same - but jeez, no explanation for the low number - WTF????

Who was your main sources for parts and your cost for the build? Would love to see a youtube vid of it on the dyno!!!

Best wishes, Tim

No question, DCOE Webers are the ULTIMATE SET-UP for sixes, can be tuned "six ways from Sunday" for HP and driveabilty. One would think they would be fairly common in salvage yards in Europe for reasonable cost, with parts and good tuners easy to find over there. True??? Here, they are VERY EXPENSIVE, hard to find gurus to set them up. Makes for terrific eye candy on any engine - inline or V-type!!! - Tim

I may have been a little low on trying to remember what these engines did put out, so I decided to do some searches, the 53 vette with 3 carbs, modified cam and pretty sure compression was also bump was rated at 150HP, a 1960 235 was rated at 135HP at 4000rpms, as I did state earlier the cylinder head is not a performer for making HP, Having someone who knows how to port these heads with todays technology along with some better cams I dont think you are going to see much better than 150ish hp and be drivable other than putting a turbo or blower on it. These motors where good touque engines but mainly in the lower RPM. Most inline 6's have a good lowend tourque. The 292 engine without heavily modding the lower end becuase of the legth of rods & Crank weight is limited to about 5000RPM, the 250 which has deffinately shorter rod and with the lighter crank can easily spin to 6000rpm, a better harmonic balncer setup will help the 250 spin even higher. There is a guy on Inliners who just recently dynoed a 292 with multiple configurations of different cams, ported heads with bigger valves, higher cr, etc got aeraged around 280hp & 320TQ and is expecting to do the same with a Chevy 250 real soon. A bone stock 2006 4200 inline does 291hp & 277TQ and with better exhaust got an addition 23hp & 15tq.

Here is a link to the 292 Dyno and another on the 250 he will be starting up shortly if he hasnt started it yet.

hi In 68 i had a 64 chevy II. I drove the crap out of it with a 194ci 6 until i broke a push rod and rocker. i went to a 250ci from the junk yard and went through it. Put in the best things from clifford. holley 600 4b full race cam with .500 lift headers. had a local electrical guy acid dip the dist. advance springs and other stuff(dont remember all). Alot of head work. Biggest thing is the center head bolt that gos through the intake port, you have to grind that down a lot. Cherry bombs under the feet. 3sp trans on the floor, G60 out back. i could take a sbc through the first two gears easily. Shift it at 7200rpm. The best thing about these motors they had 6 main caps so the bottom end was solid. All this cost me colse to $500 in 68.My father thought I was nuts.I was 18 ron

The 250 has a crossflow head, right? Does it also have individual exhaust ports for each cylinder?

Since having some experience with the 250 in a 65 station wagon I have never forgotten it. Being a fan of fuel injection I love the idea of a 250 with a 4 barrell TBI unit onit!

My 1960 261 Chevy truck motor. Dyno'd at around 155 HP. Vintage Fenton intake with matched Fenton split exhaust, 1960 Mallory dual point distributor, Wayne repop valve cover and side cover. The 261 truck motor used the 1954 Corvette cam and solid lifters. Carbs are Holly 1 barrels from a 1960 Ford Falcon. Recently installed in our 1958 Chevy Sedan Delivery. I have had more attention with this six cylinder than any V-8 I've ever had.

Great looking 6 pops....

I bored this 30 over, cleaned up the head, used a bit hotter cam, an Isky 2 barrel intake and Fenton headers. It's a fun truck to drive, has great torque, but horsepower is not its strong suit...

140 hp is probably tops on mine.

When I was in engineering school in the early 60's, there was a machinist at the engineering dept machine shop who was helping students port chevy 6 heads after hours in the shop. As I recall you couldn't do a lot to those heads, but what could be done helped a bit. I seem to remember that we figured the head porting was worth a gain of 30 - 40 hp, with the right cam and with intake and exhaust improvements. We were thinking we were getting about 180 - 190 flywheel hp considering all the improvements. The other improvements alone we thought didn't do much unless you also opened up the heads to breath a little better, as they were way restrictive. I was running a 54 Chevy in those days, but I was putting myself through school and was always flat broke, so I never did any of those mods to my car! A set of Fenton cast iron headers with dual exhaust and glaspaks and a floor shifter were about it for performance for me! My buddies used to take up a gas collection on weekends if we wanted to go anywhere. Putting 85 cents worth of gas in my car would at least get us to the bowling alley and back with our dates!!!

Fun days, but I do wish I had gone ahead and found the money somehow to try those mods myself so I could speak from personal experience. I did ride in some of my buddies cars back then, who had made all the mods, and yes, there was a definite improvement. Those modified sixes were very strong off the line (referring to the "stoplight wars" of the era) but ran out of power pretty quickly!
Aloha,
Let us know how you do with your 235.

I have the same set up as Todd M in my 53 3/4 ton truck , that along with a newer Suburban rear .... it moves along right nicely .

The sound comes as you shift gears so learn to double clutch
Looking for any information on the Chevy One Ton Humpback Panel truck.... Anything would be helpfull

...the 250 which has deffinately shorter rod and with the lighter crank can easily spin to 6000rpm, a better harmonic balncer setup will help the 250 spin even higher.



The 250 has a crossflow head, right? Does it also have individual exhaust ports for each cylinder?



The 250 does not have a cross flow head, there is an aftermarket head or one from brazil that is called a 12 port head. As someone else mentioned on these 194,150 & 292 head the head bolts go through the intake port. Removing this and use of either a bolt in lump ports or short allen head head bolts increase airflow, stock airflow on these intake ports is about 170cfm, with porting you would be lucky to pull about 180cfm, removal of head bolt boss and short head bolt is aout 200cfm and adding in the lump port kit flow is usually around 225cfm without any extensive porting. Lump port kits can be gotten off of ebay for around $120ish shipped and come with everything needed except tools to do the job. 194 heads have small chambers but dont appear to gain a whole lot when installing on the bigger cubed engines vs the stock 250 & 292 heads which have 72+CC chambers. Heads can usually be milled safely .060, some racers even mill as much as .125 off the head, this is not recomended for the street use.

Here is the state of the project.



I don't know the specs of the cam, but I got it through Patrick's in Arizona. My parts came from the 4 corners of the country. I am hoping that it will put out better than 150hp.

Clifford Performance's says 6=8. The 235 is not their top pick for Chevy's but what the heck you have it bought and payed for.
