Not much more power but more torque.For some reason this motor fell on its face at 6100 rpm when even the flat tappet made power all the way up to 6500? Wtf?
Im getting the 5% overdrive dyno pull faxed to me, but just for now the apples to apples comparison has the flat tappet beating the roller by 15 peak hp.
Heres the pulls
