Ok heres the deal. Performance parts for the olds 455 are few and far between. I was thinking today "What if I just put in a chevy 454?". I wanted your guy's (and gals) opinions. I have heard that the cylinder walls and cooling ducts for the olds are superior to that of the chevy, can anyone prove/disprove this?

If I remember correctly hotrod magazine had a shootout between a pontiac 455, chevy 454 and buick 455. All had identical bolt on components and yet the buick thoroughly handed some ass. Are the designs of the motors in GM that different?

The reason I may switch motors is because pretty soon I am going to have some cash, so I was thinking of building up a motor and dropping it in. I have thought of a cadillac 502, but dont know how hard it is to build them up. From what I understand that motor is frequently used as the base block for drag cars...

So I have 3 choices. Use my 455 olds and build it up, use a chevy 454, or a cadillac 502. Keep in mind this motor is going to be fairly low compression because I am definatly going to supercharge this monster.
