303 engine build help
hey guys. i have a 1953 olds rocket build in progress. it has .030 over pistons and new stock lift cam. the cyl. heads rebuilt. i want to get the most power out of this with reasonable $$$$. the heads are bare. i'm thinking roller rockers, roller lifters, custom headers/dual exhaust/cherry bombs. i dont have the 4 bbl. carb. yet.
if anyone out there with experience with these engines could help me out, that would be great. i'm putting this in an original 53 super88.
thanks alot, dan

http://rossracingengines.com/ might be able to help, they specialize in these engines, along with the 324, 371, 394.

You will spend a lot of money for not much gain, 303's can be made to run strong but for strong money and you need to plan your build from the ground up. Ross Racing can be your best adviser (Kevin). The hydros in the 53 aren't as strong as the 54-56 slant pan hydros, if you get to your HP dreams you might want to swap transmissions because it won't last long if abused.
If it were mine I would look for a good 371 core and build from there, 300 hp to start with and it should be a near bolt in. With a little cosmetic work it could be made to look as a stock 303 ,Quite a sleeper. Just my thoughts... Lost in the fifties ..Tedd

The single biggest thing against any year Hydra-Matic is the cork frictions stock units use in the clutch packs. Cork frictions belong in one place today, in the wastebasket. Most of what made a B&M or any hopped H-M much more reliable in this use involves using Raybestos type waffle cut frictions, which used to be expensive and special order. Today these and the ruddy red solid types are all you can get, thankfully. Fatsco has Raybestos type, Northwest has the red, both work well in my experience.
P.S. If by slim chance your 1953 engine has a four counterweight crankshaft, I would love a pic of it. Thx
