Obviously Im a newbie...81 cut and 72 cutlass drop. If this is not the rite section for this subject let me know.


I have a stock 350 in the 72 cutlass I just bought. Basically I want to clean it up, dress it up and add a little horsepower without having to pull the motor. Mechanicially the car needs nothing but a lil carb work. rides VERY smooth. Im thinking intake manifold and carb. Headers, new exhuast and the normal dress up kit.

My question is what Manifold, carb, and headers should I go with and what will this do to the power in my motor? All my buddys are Chevy guys and their suggestions are irrelevant because they dont know olds motors.

Any help and/or advice is appreciated. Thanks!!!!

I guess that means an 81 Cutlass with a 1972 Olds 350 dropped in it.

I think I saw in another thread, that you put the 4 bbl on it already.

The next thing I would do, is RE-GEAR the car. You probably have a 2.29/2.41 differential gear in it. If you no longer have the overdrive transmission, you need to get at least a 3.08/3.23 gear in the car. Even a 455 will not smartly move the car, with the gears you have. If you had a 3.73 gear in the car, you would have said so. You should get a 3.73 if you have the overdrive.

Dual exhaust. Headers are a +, but just a dual exhaust will be beneficial.

Re-curve that distributor.

No I was saying (Matter of factly) I have 2 cars. 1981 and 1972 cutlass's. I have a numbers matching 350 in the 1972.

The Edelbrock performer works good for me, but I don't have headers so can't help there.I did upgrade mine with a Pertronix kit to replace the points and it was worth it to me.

warhead, please explain recurving the dist. I have upgraded mine (also a 72 350) to a 4 barrel with duals and headers and a pertronix kit. the rear end change(3:42) is next in line for funding!

im new as well but my experience i had a 77 cutlass i found that i put a edelbrock performer aluminum intake with two one inch plates and 600cfm edlebrock carb and i had imidiate horsepower without pulling the engine i didnt put headers on that one i endid up selling it after i put my foot through the floor lol. Can you help me find a 75-77 olds engine harness? thanks

ended up going with the performer intake and 600 cfm carb. It added a lot of torque but not alot in top end power. I will be changing out the rear end though! Only problem is i think I gota play with the choke more. I have to pump the gas to get it to start a lot even after itas been driven all day.
