Thanks for the information. I'll use the Wallace calculator. When Howard and I think it's lunati show 112 / 108 on their website are they giving the LSA/ ICL numbers?
Correct. You can play with ICL to get the IVC where you want it. It's not uncommon for many builders to run more than the typical 4 degrees advance, and the window for advance/retard is larger than most assume. P-V clearance is usually a non issue with off the shelf cams, but should always be checked anyway. I'm running ~300 adv duration and ~.600 lift and still have well over .140" p-v clearance.
