The parts from Danchuck arrived, they are almost identical to the old parts, so the 4 inserts in the new kit will not be used, as the old ones are still in good shape and are pressed into the steering arm and the drag link.



The one exception is that the bearing adapter on the bottom of the idler arm at the frame has a grease zerk on it, the new parts do not, but this grease zerk hits one of the header pipes, so I pressed it out and rotated it 90 degrees or so toward the motor so it would clear the header pipe, and pressed it back in....



Cleaned up, fresh grease and new bearings on the frame mount end, now to do the drag link end....



More Later...

Update,
Discovered that the drag link at the idler arm does not have a grease fitting, so am drilling and tapping for that, here's some pix....

The March Performance parts showed up, this is the install diagram:



Here's the parts that came today (below), there's only one set of idler rollers, there should be two, let's see what March says about this, I can't make this work with only one set of idlers, look closely at that diagram above....

Removed the steering idler arm assembly and took it apart...



And found that the "upgrade" ball bearings have been added, replacing the OEM bushing system. But the bearings are worn, dry, and have not had grease in some time, so a new ball bearing set is on order from Danchuck, should be here any day now...

In the meantime, I need to drill and tap to relocate that grease fitting where it will not hit the #4 header tube...





I pack mine same as a wheel bearing. Takes longer, may last a lot longer!

It's all good. mostly

I do too, makes sure the bearings are thoroughly greased, but will still hit all the grease fittings with a grease gun before hitting the road for the first time...

Unfortunately, the Vintage Front Runner system is not available for the Chevy LT1 motor series. That front mounted Optispark ignition setup will not work with any of their systems, I checked them out, as well as a whole bunch of others. March Performance (MP) is the only one with a system that works with the LT1, and I needed the Corvette LT1 front crank pulley with their system, as it locates the serpentine belt further forward then the Camaro LT1 crank pulley does. I'm using an ATI front damper, and had to swap out the Camaro flanged damper hub for a Corvette version in order for these parts to align properly using the MP setup.

MP has admitted they screwed up by only sending out one set of idler rollers, they have another set on the way so I can complete this installation.

We'll see just how well it all works out...

Played around with the power steering pump orientation, started out with this as indicated by March Performance:



But there are obvious problems with the hose connections and the a-arm mount and the header tubes...

so tried this:

Still have hose problems with the alternator and the header tubes...

so tried this:

I can make this position work....

Improved the alternator mount, as for some reason MP sent me
an extra adjustor rod adapter, so I used them both....


And changed the mount for the AC compressor to this:

Spacers will be added on that bolt each side of the adjuster rod...

Got some more work done....






Had to do a bit of remedial work to correct some deficiencies in the way these MP brackets were set up, and had to wait for some parts that were not shipped with the initial order. But I'm pretty happy with the way the setup is turning out.

Still waiting for the new Corvette style LT1 flanged crank hub to arrive from ATI to replace my Camaro hub, which will relocate the damper further forward and align it with the MP LT1 "Outward Mount" pulley system.

The Camaro LT1 hub I'm using here is temporarily located in a forward position in order to facilitate the fitting of these other MP components.

Lots More Pix HERE....

It's an LT1, a 93 out of a Z28 I bought new and totaled about 5 years later, kept the motor and tranny out of the wreck. I got lucky and walked away from the wreck, nobody can figure out how...

LT1 motors have an Optispark front mounted ignition setup driven off of the cam, and the water pump wraps around the Optispark and is directly gear driven off of that. So basically it is driven off of the cam.

This is not a very good picture, but the Opti is the sickly yellow looking item just above and behind the crank balancer...

and just above that sickly yellow portion on the aluminum housing you can see a stub shaft sticking out...

It is splined and drives the water pump...


Part of the reason nobody wants to make brackets to fit accessories on an LT1/LT4 motor, compared to other SBC motors, it's a pretty special fit. So far I found only March Performance who would do what I needed, and I tried everybody I could find!!

In the meantime my '58 prostreet Chevy pickup is giving me fits, had to pull away from this project for awhile....

Willy

Ahhhh.....now I understand how that waterpump is driven.
It keeps the front clean (one less pulley).
What's wrong with the 58 truck?

The 18 yr old exhaust system was rusting out, non coated headers, etc, got some new coated headers and put in a whole new exhaust system. The new headers are routed much closer to the pan/tranny, which also puts the left side right up next to the under floor master cylinder. First day out it boiled the brake fluid in the piston chamber dry without me knowing it during a fairly long run without touching the brakes. Coming up to a busy stop light, wow, no brakes!!!
Lucky there was a wide grassy medial strip and I was in the left lane, into the grass and down shifting (th400) to low and then to reverse, got it stopped without hitting anything or anybody or wrecking the tranny!!! Flatbed trip home, and of course waaaay too many of my buddies saw that trip home on the flatbed!
Once it cooled down the brakes were back! No problem with the brakes, so I wrapped the exhaust next to the master cylinder with hi temp exhaust wrap, that seems to have solved the problem. Also got some high temp brake fluid, I need to flush out the old stuff and put this new stuff in.

But it has started eating fan belts, 3 belts in 3 weeks, the last one lasted a half hour. That one wrapped itself around the flex fan, bent one blade, and started eating into the radiator, no leak yet but a close thing. Pulleys all look aligned, don't see what is the problem! Just got a new flex fan, will put that in with a new belt and see what gives. Also am going to sand paper the pulley surfaces, they are all pretty shiney looking, polished surfaces, want to rough them up. The water pump and alternator and power steering pump all turn by hand easily, don't see anything hanging up, nothing has been changed in the last 18 years, so just can't figure what is up with this. Maybe the NAPA v-belts I'm using aren't worth a damn these days??

The serpentine belt I got for the Lt1 in the hardtop is NOT a Napa belt, March Performance recommended strongly against the Napa belts....
Got a Goodyear belt instead.

But since this is my main rig to haul my surfboards and my one man outrigger Hawaiian ocean racing canoe, I haven't been out on the water much this last couple of months. Need to rig up another ride to haul this stuff...


  • 4dr 57 Said:

Yes, put a model 500 steering box on and it looks good for clearance, etc, and hooked up to the steering parts no problem. Just need to plumb the hoses and hook up the Ididit steering column...

It's been awhile since I bought them, and I can't find the receipt, but....
I'm pretty sure the headers are Hooker Super Comp full length # 2112-1HKR.
It's a snug fit but I got them in and clearing everything with a minimum of adjustment and without having to put any clearance "dents" in the headers.

Haven't picked a master cylinder yet, will need to make that choice and purchase soon....

Meanwhile, ATI sent the wrong hub for the revised crank damper setup that I need....

My Camaro LT1 hub is on the right, according to ATI that left hub is a blower drive hub for a small block Ford, don't think I can get that to work here...


That's the Ford hub on the right in this pic....
Larger OD crank snout, different drill pattern for the damper mount....


The give-away was this part number on the new ATI hub, ATI says it is a ford small block blower drive hub....


But the box it was shipped in had the correct part number on it for the flanged hub I need for the Corvette LT1 motor...


So now I have another delay while I ship this part back and wait for them to ship me the correct part...
Aaarrrhhhggg!!!

Family issues have kept me away from this project, and I really miss it, I need to get back on it.
The problem with the balancer flanged hub was a downer, and ATI is taking care of it, the "correct hub" is supposedly being shipped to me as I type this.
And it will get done...

Finally got the correct ATI Corvette LT1 flanged crankshaft hub for the damper today. It is quite a bit longer than the Camaro hub...



The holes were all in the correct location, and the damper bolted up to the hub correctly....





Now to see how well it aligns with the March accessories mounting system...

It turns out that this new ATI LT1 flanged hub is seriously too tight for the crankshaft.

As the older ATI LT1 (Camaro version) fits normally with no problems on this crankshaft snout, the problem is with the ATI hub.

Right now I have a broken bolt inside the crank from trying to install the assembled damper with the new hub, and a stripped damper puller from trying to remove this hub after breaking the installer bolt.



I've had this damper puller for many years,
it takes a serously too tight hub to cause this center bolt on this puller to strip the threads like it did on this one...


Here's some sketches from the first install attempt, showing that I still needed to go about another half inch to get it on all the way, that's why the crank pulley didn't line up with the accessory pulleys...


Now I have to disassemble the damper from the hub, and heat the hub to try to loosen and remove it, and then remove the broken bolt stub from the crankshaft...

Am I having fun yet???

Can you use some longer bolts on the puller where it attaches to the hub, in order to get "better threads"? My hub puller is the same one; I bent the threaded shaft trying to remove the dampener on a 454 a few weeks ago. I had to go with a pneumatic impact gun to keep from bending it. I don't have a dampener installer tool, and use the 2 inch thick piece of 3 inch round bar, and a BFH to "tap" them on. I wedge a block behind the crank flange to help protect the thrust surface/bearing. Good luck getting the dampener/hub and the broken bolt out. That's one bolt I've never broken (knock on wood), thankfully. I am Butch/56sedandelivery.

Hello;
Made off shore?
I see lots of great looking parts that eithor don't fit right or don't work as intended they all share the same thing, "Made off shore"!
I also know that off shore producers, (this goes for car parts to the fruit and vegetables you eat) are making it more difficult to "find" out where they come from!

It turns out that ATI is making the latest "Super Damper"s with an "undersized" interference fit, requiring a machine shop to hone to fit on a Sunnen rod hone.

Here's an excerpt from a document on the ATI web site...


OK, a visit to my local machine shop on Monday...

Just a real long flex handle when it came time to switch over from the ratchet....

Today:
Quite a few hours with #100 gray wet/dry sand paper, then smoothing with #600, took out about 0/0008" to 0/0010", then did an assemble with just the flanged hub and assembly lube....
assembly lube on the 7/16 sae threads inside the crank snout also, used a 5" by 7/16" bolt and kept adding spacer to push this on, tight but not abnormal in my experience...

Very cool build, I cant wait to get back to working on my 55!
I thought I was the only one still running LT1s, I put them in a few of my cars and more are in progress. Looks like a lot of hassle dealing with the aftermarket FEAD, I stick with the factory stuff. Only thing I have not tried yet is I want to see if I can make a vintage air Sanderson compressor work with the factory LT1 bracket.
Why wouldnt the factory FEAD work? Other than the valve covers I dont see any issues.

  • drptop70ss Said:

I used the Earl's side motor mounts, they fit quite nicely, and use the more forward side mount holes on each side of the motor, where the accessory bracket also mounts on the LT1 Camaro motor in this picture. The AC compressor and the PS pump are mounted closer in to the motor and tucked in on the right side of the motor, causing interference with the headers and the motor mount and the upper a-arm mount of the '55, as well as the tall valve covers I am using. As I also have about six other projects going on, and did not want to take the time to measure, design, and fabricate brackets to try to mount the original accessories out of the way for this project, I started hunting around for brackets that would work. I did not know that this LT1 motor was considered such an "orphan". There is very little out there for accessory brackets for an LT1 in a tri-five Chevy. The longer damper hub for the LT1 Corvette pushes the belt and pulley location enough further forward that it is easier to setup the accessories with less interference with the motor mount, etc. If I wasn't so involved with these other projects, I would have loved to take the time to do my own brackets, but as I am working on this car in a friend's shop, I need to keep it moving along and get it finished. I recommend finding a Corvette LT1 balancer and starting with that if you are going to do your own brackets.

Here's what I was looking at when I started thinking "brackets",I pulled this out of a totaled '93 Z28 Camaro (mine!)....

Starting at the balancer, and going left and up, there is an idler, the AC compressor, the PS pump, and the alternator. I'm certain that none of that would have fit in my '55 chevy without extensive modification, or a complete redesign of the brackets and accessories setup. Just taking some simple measurements I could see that it would hit dang near everything in the 55, cross member, motor mount, header, upper a-arm and mount, valve cover, so I started looking for alternatives. I'm sure others have run into this same problem, with that Optispark and forward mounted water pump causing interference with many of the easier routes for the drive belt. I got turned down by at least six manufacturers of alternative bracket mount systems as soon as I said "LT1 in a '55 Chevy". March was the only one I could find with a system that actually worked.
Just for comparison:


I started out with just an order for the basic brackets, in black, but as I proceeded I added an AC compressor and a PS pump, just seemed quicker to get the job done. I did not expect to run into the problems I did, like them shipping the wrong part, and then finding it was intentionally undersized and needed honing to get a proper fit. That was rather annoying, to say the least!

If you do take on the brackets project for your Lt1 in a trifive, I'd love to see you post it here where we can all follow along.
Good luck,
Willy

I guess I have been lucky so far! Other than frame notches for the A/C compressor I have put the LT1 in a 70 chevelle, 68 chevelle, 65 442, 47 cadillac ( G body suspension), and a 41 cadillac (jag front suspension), and two Ford F1s with no issues using the GM brackets. I make my own engine mounts so when the time comes I will sit the engine where it has the most clearance. From the look of your pictures it looks like I would have to raise the engine some but not too much. Those aftermarket brackets look great but dont fit my budget
