Quarter Mile Gear Selection
Just stopping here to wait for the "we don't race dyno's" crowd.
The best way to know what gear you need is by doing math. In order to have accurate numbers for the equation you need to know where the engine makes peak hp and how well it carries the power band.
I am thinking you will be close to 6500 rpm max with that cam unless it is unusually long duration with a wide (112, 114) LSA.
If I were tring to shoot in the middle (6800ish) I'd look at a 10.5x29.5 stiff wall slick. MT p/n 3062.
