I run a 80508 750 w/ VS on my car with stock jetting (same as 3310)...no problems. Cams are pretty similar and I have a 440+0.60 over. Timing is set about the same with no vacuum advance. Runs about 190 cruising on hot days.



yah i'll admit that i may of jumped the gun by saying that he's runnin
to small a carb. BUT unless one of the fuel passages is clogged,
or he didn't read his plugs properly, going up that many jet sizes
dictates a larger carb is needed. i HATE inter-tuning
