If the heads are not going to be ported, I think the cam that zippy suggested is a good one.. I think a general rule with LSx motors if if you have the valve springs to support it, is run a more lift. LSx motors respond well to the cams with higher lift numbers even if the durations are the same.

That's not nearly close enough. That cam would be alot of fun if you plan to spin it to 7k or higher and don't mind an idle of around 1k or so.

You're getting closer, but I'd go with more split.

99-TR-BLOWR-CAM Thunder Racing Custom Camshaft

"TR Blower" - 214/230 .601/.579 117 LSA. Off Idle-6800 RPM Power Band. Broad power range. Different from our CheaTR with even less valve overlap for forced induction applications. Stock like idle
