Inliners International Forums General Discussion Hi Performance One barrel vs.Two barrel!!!

Hey guys, recently my old rochester one barrel has giving me fits with backfiring after I cut the engine off i got the timing set nicely, and check everything else. i thought about puting another rebuild kit in it. Or i thought about the Holley two-barrel carbs. Would it give me any kind of performance over the stock one barrel??? And what would I have to change up?????

Thanks,
MATT!
