Put 100 miles on the new pistons and jug today, Ran a Rev8x three times to about 100-105, I am running 153 studs, he had 168, these two sleds are close, what can I do to get him in midrange? out of the hole he kills me! This REV8 hooks up great, I have tried sitting way back on the seat and adjusting the blocks, He told me he has some clutching done to the primary only, We switched and the same thing, we both way about the same, 220-240. The REV is different, not bad but not a cat.
