12 Second N/A Slant 6?

I have over 1K in my head including all machine work, porting valves and parts. The benefit or roller rockers on the slant is really nothing. This has been fought over a lot. Call Rocker Arm Services and talk to Gary. Then can make you anything.

and as i said the roller part, not much gained, the LIFT on a low duration cam is the benefit! but we have already made that game plan up..
