havnt put much time into it. But this is as far as I made it.
Baseline: Governor removed and Predator carb 42.4mph
dropped gear ratio from 8.07 to 7.62- 46.3mph
Removed fan and advanced timing 47.6mph
All testing was done with my heavy ass onboard weighing a whopping 270lbs. lol
I think the valves are floating, so I will add valvesprings, shave head and build a hand ground cam tomorrow if time permits. That should definitely get me 50+.
