Vauge, what carb, intake and cam with what size tires?

You also realize this is a 318 questioned thread?
750 mechanical secondaries,strip dominator, 509 hydralic, cheap hedmans, hard *** tall firestones, yeah sorry but this stuff can go on a 318, My point was the 340 was a stock bottom end, not touched with lots of miles.
