Alright...awesome explanation...appreciate the details...great stuff, thank you! For those interested in further details check out the following HotRod mag article.

I pulled up my HE3844AL cam card, the specs @ 0.050" are a bit different from what you show, but at the end of the day what you walked through still holds true.

So, here is what I have:
IVO is 13 ° BTDC ( - indicates ATDC)
IVC is 44 ° ABDC
EVO is 53 ° BBDC
EVC is 11 ° ATDC ( - indicates BTDC)
Overlap is 24

I'm curious, where did you pull/obtain the CompCams roller cam duration number from? They only show the adv duration numbers on their specs page...LOL...go figure, by now I think everyone looks at the 0.050" numbers to compare cams, or am I wrong?

OK, so the plan at this point in time is for me to do a season's worth of test&tune on my current cam. I am moving back to my Performer RPM intake (from Strip Dominator) to get back some of that low-end grunt I lost. I hope that will get me into the 12s...beyond that, I will most likely try the roller cam and do a 'side by side' comparison so to speak.
