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.

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

Cool !

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

We didn't. It was already done due to the exsisting 55mm cam.

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.

No actually a long time ago when all of the techs were pushing to light of springs we started bumping up the pressure to keep the lifters following the lobes. That's just where we ended up trying to control the cams we were/ are running.
