The supercat engine we took apart had solid crower rollers on a 55mm cam. Odly enough, they were .842 diameter.

I sold them on eBay as I had no idea how much time they had on them and I wanted to use a .903 solid roller.

I bought morel as they are local to me and Ed was present at the machine shop when the bushed bores were opened up for the bigger lifters.
Dyno time only so far

That is good life. What where you using for valve lash ? Plus, I'm assuming rocker shaft set up ? Edit in: LOl, just saw the 1000lb springs so definately shaft rocker.



Cool !

Did you do the oiling mod like Black Baja just spoke of ?

The H in the Crower part number is for the high pressure pin oiling option, never run without it. Valve lash was .016 hot, intake and exhaust. Definitely shaft rockers, T&D and Crower stainless.
