Camshaft Experts

You need to know what those #'s are, valve to piston clearance, and what intake centerline that cam is installed at. With intake valves that size, Newbomb's spec is 8° tighter & advanced 3°, plus if You add more rocker ratio...those intakes are going to be popping open way sooner & higher. This is no time for guessing about it, it needs measured before doing anything else.

That will be checked when it's being worked on by my engine builder. I just don't have those specs at my disposal from the last time the engine was done. With the new Jesel, the plan is to check vtp clearance at 0, 2, 4 and -2, -4 and then so long as it's sufficient, do pulls at all of those settings.

In the meantime, he wants me to take a compression test before the engine comes out. Wants to see 180+. If it's under that, I assume we will have to go a little further and get the compression up.

An interesting update, the owner at BLP Racing products (who is making my new carb) stated he has seen the best results on Mopars retarding the cam timing. So i'm interested to see what my engine likes.
