hey everyone, im 18 from IN. Ive been around engines and rebuilding them for quite sometime now, but i have never done anything with performance. i have a 1971 oldsmobile cutlass i got about 1 year ago, recently the engine went out. i just purchased a 1970 455 for it. but it needs rebuilt and i was wondering if anyone could tell me the parts and where i could get them for the most performance out of this 455. if you could i would greatly appreciate it, thanks.
