    Hi all
    My son has installed a '75 Buick 350 engine in his '79 Camaro (ya think Dad had anything to do with that idea???). The stock carb has been rebuilt but still has a bad flat spot if you hit the throttle too quickly. I do know where there is a '73 Riv GS 455 with the carb. If we grab that one to rebuild and put on what else needs to be done? Will any jets have to be changed etc? The 350 runs great but we are just trying to get some more umph out of it and the bogging carb seems like a good place to start (buy getting rid of the emission choked stock '75 quad one). SUggestions? Thanks in advance!

    Have you done any mods to the 350? If not you may need to change the jets. I would try it and see how it runs. The 73 455 carb is better for performance, also it is 800 CFM.
