I've been checking into pump p/n's other than what I posted & compair to Rock Auto's catalog. I've seen a few different p/n's for SBC V6/V8 applications (B, C, & D bodies) in the GM catalogs but remans list one to cover almost all of GM's. Olds gas V8 used 7840244 (A/G, B, C, D, E bodies. E also has a remote resevoir verson p/n 7830304). Buick V6 (should be used on V8) used 7839345 (A/G body).
