Hey
I will describe it a little better then in the wrong forum place.

The easiest is just to swap the cam or buy another engine, but what would I do with the things I've got to reduce the missmatch pancake I have.

Car is to heavy, gear is to high, stall too low, heads to big.

Car: impala 63, th350 (2500stall), 10bolt 3.08or3.33 rear end, 22" tires, headers and 2.5 free flowing exhaust.

Engine: 327, (from start a 350)
570 street avenger
Wieand dual plane intake 8150
Pro topline heads 64cc 235cc
Forged dome pistons
9.5 comp
Comp cam 12-705-8 solid roller
255/255 duration
575/575 lift
110 lsa

I've bin running this engine for the last 3 years and one roller broke and toke the cam down the drain.

So now i can maybe build the engine to match the car setup. Drive it around 1700-3500rpm street&highway and now and then give it full throttle.

How would you do it.
And yeah, now my car budget is $1000

Clean it up and put in a relatively mild hydraulic cam (flat tappet would work here) and it should run pretty good. That cam you had is too big for a 327 unless you're going to be turning it some serious rpm.

I know this is not engine suggestions, but 700R4 would make a big difference in drivability. And/or a 3.55 rear gear ratio.

I would clean it up and stab in a different cam and lifters as well. You want to get a cam that produces power in the rpm range you will be driving it the most. And I agree that an overdrive trans will help you enjoy driving the car more, but not really needed if you do have anything below 3.50 gears. But it will improve your gas mileage. I would change the torque converter at the very least. That converter is for launching the car in a drag race. If the engine is turning below the stall speed you transmission will effectively be slipping all the time and running hot.

you would have much better results with a cam like this crower hydraulic roller
https://www.crower.com/camshafts/chevy/chevy -262-4...
a 3000 stall converter and ideally a 3.73:1 rear gear, no it won't sound as radical, but it will be faster and easier to drive, given the budget ID go with the cam/lifters and converter and save for the rear gear swap

IF YOU CAN , YOU NEED BETTER TIRES AND YOUR SUSPENSION NEEDS MORE WORK!!

Thanks for all replay.
I do have th700 in my mind, since I'm running at 3000rpm in 60mph so it would be slick with one more gear and lockup.

I'm little little against lower gear since I have 22" wheels. Because the car is bodydropped so limited space between the asfalt and fender (23") you can see the wheels in the pic.

Will my 235cc heads be a downside with a smaller duration cam. I'm looking out for cams between 115-228 in duration for low powerband, kind got stuck in my mind with roller but go hydraulic.
But flat would suit the wallet more

a 200 r4 will basically be much easier to swap to from a th350, the large port heads will not be nearly as much of an issue as you might think.

The heads aren't ideal, but you won't be changing them with a $1000 budget unless you find someone who will swap a different set with you.

If you don't change transmissions but change stall then do look at a higher quality custom built converter, not a parts store off the shelf. They can give you the stall but not have it slip so much at lower rpm.

Yeah there is no problem to get a custom built one. I believe it would be around the 1800-2000 instead of 2500 as I have now.

I remember when I started the engine the first time and put it in drive with my stock converter and it jack rabbit jump and died

No, I mean for example you can get a 3200rpm stall converter that will drive with low throttle and you would hardly know it's there driving at say 2000rpm. That is compared to a cheap converter will hardly drive at all below it's stall rpm. Of course, a $1000 budget kind of kills doing that. Personally, I'd try a new cam and see how it runs first.

If you decide to go with an overdrive transmission, you will probably hate it with 3.08 gears. You won't be running enough rpm for the cam for highway driving. That's why lower rear end gears were recommended. You might get away with it if your rear gears are 3.36 ratio like a lot of cars were at that time.

Thx for your respond

If I pic a 1800-5800 rpm band, would that be to far of for a th700.

I know I run at 60mph at 3000rpm

And when I use www.markwilliam.com calculator I can't have a 3.08

Tires-22" th350-1.00 rear-3.08
2550rpm at 60mph

Tires-22" th350-1.00 rear-3.36

Tires-22" th700-4gear-0.69 rear-3.36
2150rpm at 60mph

Think it is a combo of 22 inch RIMS plus the tires?
Would change the math. Say two 3 in. sidewalls and you end up at 28 in.

have you considered swapping to a BBC engine, a very mildly modified 454 would do amazing things to the cars performance and most likely at lower cost than rebuilding the current combo with parts required, especially if you can find a donor car/truck.motor home
\ about 50 years ago, I had a 1965 LEMANS
that needed a transplant

Your first questions were engine related and the picture of the motor I guess I only saw the engine. Now with the picture of the whole car I rushed back to the engine picture and REALLY looked at it. Ah yes the top of the dist is above the cowling and the upper control arm is high compared to the body etc. I had a good laugh at myself.
I like the pic of the whole car and with your tire size your rpm vs mph seem more in line.
Thanks for waking me up. Now tell me why I keep thinking of Norway?? I just turned 80 so don't put any money on me. Mel

Well well Almost, its Sweden
I've have build on this car for the last 10 years, and that is not body work as you can see
Every Winter is the challange to get it lower, or just fix the importen things. Fram, rear, front susp, wiring and so on. And last Winter i was tired of everyone had did a kickup so I cut the rocker panels and dropped the thing 5,7" over the frame.

And now a new area starts, learn about engine with mild performance and how everything have to match.

Not like over the years, buy a motor, bang, new rear end bang, new trans bang and understand later on is a missmatch but hey. Its never too late to make thing right and have a cool slammed ride that can run out from a friend with std 350

If you could find a van with a L31 350 and a 700R4 then it might be worth getting that drivetrain. 327 to 350 will improve torque and the L31 is a pretty good short block to start with. Already a roller cam so just stick a bit bigger one in it. The GM factory roller stuff is a lot more reliable than aftermarket roller cam swap parts and cheaper too.
