Patrick G just look him up on here.
I am building the same cubes as you but with L92 heads. I went to Geoff since he does all my tuning and he spec'd my cam. His lobes a proprietary to him (EPS lobes) and they make pretty good power with minimal valvetrain noise.

I'm going with a comp 243/259 .624 lift of both sides with a 114+3 I believe it's part# 54-472-11 and grind# 293LRR HR14. This is what Brian at comp spec'd for me when I called him.
My build is similar, 416 -2cc reliefs, and LPE HEADS milled for a 12-1 comp. TSP 1 7/8 headers.
According to Comp the Ls3 heads need a minimum of 12* to put down some good numbers. I ran this by a few LsX builders and they agree. So I'll be running that with the FAST 102. I can't wait to post my results.

Some split is needed but I don't think that much, but what do I know Geoff@EPS has cams with 16 to 32 degrees of split and they make power. I guess its all in the combo.
