hey everyone,
I just bought another big block but needed to verify the heads that are on it. Found a website that had the info I needed but also noticed it had all the casting numbers for pontiac, oldsmobile and buick along with chevy. Hell, they even had the ORIGINAL numbers for the pontiac tri-power setup for the carbs, linkages and modulators, etc...Nice to see all the gm numbers on 1 site. check it out www.gmclassicmusclecars.com (http://www.gmclassicmusclecars.com)
