I thought I wanted to drop a 455 in my 72 Cutlass conv, but I see I will have to change a lot more than just the motor. So I have decided to beef up the numbers matching 350 motor I have. Any suggestion on what I should do to get more from this engine. I have a 350 TH trans that is already in the car with a shift kit installed, a 4 barrel carb, dual exhaust with 2 1/2" pipe and dynomax mufflers and a HEI distributor and H.O. coil. This is not enough. PLS help.

 

ive got a 72 cutlass supreme and i put a "p.a.w" house cam an edelbrock intake holley 4 barrel carb and im looking for a set of headers but that proves impossible well put together the combo ive got and see how u like it

 

Chris, no matter what the books say, headers for your 72 supreme are the same as the headers for a cutlass or a 442 w/ the 350, chassis are all the same. Don, you have done just about everything that you can do externally,now it's time to add a good street cam and rearend gear change to add the oomph that you're looking for.
