what determined what carb went on a 325 hp 4 speed holley or quadrajet.

I think it had more to do with smog control I believe, California with A.I.R pumps had quads where Kansas were more Holley's, and trans selections might of had something to do also.

I believe they were all Holleys , except for as Rock says... on Freemont built cars with A.I.R.

I think there were also a few other "Rochesters" produced... I think the "3-letter" suffix codes... AIR engines used different codes, so no need for the extra "H" or "R"... Don't have the info in front of me...

But yeah, mainly smog cars...

Hi Jack. You might try psoting in one of the forums rather than in the welcome forum. I think you got some good answers here but more info might be available in the Tag Team forum.
