Looking at a replacement carb for a rochester q-jet for a 308. Its been recommended to use a Holley 450 square bore model 4360. Been told its a double pumper which will work well with my manual hz sedan with a 3.55 diff. The motor is mild, looking for a bit more go.
Will this carb be alright?
Thanks,
Ado

Stick with the Q-Jet, much better than any Holley.
Just get it tuned by someone who knows them.

If at first you don't succeed, just call it Version 1.0 |

not sure what model 4360 is,
but i had a 450 holley, annular discharge model on a HJ statesman, 308, T400, 2.78.
it wasnt a double pumper either.
very economical, but grossly underperformed.

Looks like the rochester is the go! Had a Carter thermoquad on my Kingswood once upon a time. That went well and was very tuneable.Could be time for a Quadrajet.
Thanks,
Ado.
