Yeah the 232/236 cammed car you had a little run with shows exactly what a big cam will be like. With a smaller cam you would of smoked him till about 140 then he would more then likely run you down
Larger profile cams will produce more power at mid-high rpm, and this has nothing to do with overall speed whatsoever as small cams can still beat a big cammed car,
imo for an L98 motor you cannot go passed a wide split pattern camshaft with high lift - the duration will be up to you
