I am not saying to run a hydro roller, BUT, I went from a solid FT to one in my 512, used one from Hughes, 9.7to one, 4050lb street car,
solid cam was 248@.050 116 mph 12.03 2200 DA
Hyd roller 255,258 @ .050 121 11.33 mph 1750 DA Short shifting 5500, easy pass
but I used the expensive High RPM Morel.
Still need to do some track tuning.
also had better rear tires for the faster pass
