Why i ask is my stepson called me. He is visiting a friend
and the friend bought a Impala with a 400 sb with some
camelhump heads and flat top pistons and a "cam" but
just a 500 edelbrock and they wanted some more go
so i told them to buy a 750 Holley to begin with
They called and had bought a 750 holley cheap on a swap
and sent me pics.....it was a Pro Form with Holley float housings
Looks "racey" with no choke and exchangeable air corrections
I'm afraid they bought someones problem
Any one having any info about stock jets,air corrections etc
