A friend of mine is trying to go with a bigger cam in his 402 ls2 stroker motor. He had the g5x-3 and now wants more. His short block is a 402 ls2 block with diamond pistons with -2cc reliefs. 6.125 rods and the tops of the pistons come out of the deck .005's. He has livernios stg 3r heads with springs good for 670 lift with chromoly 7.4 pushrods. He has stock rocker arms now but plans on goin with some terra's once his heads are done from the port shop. Any ideas on a good sized cam to get the most out of this 402. He made 485rwhp n/a on the last setup with low timing so he can run spray. He plans on keeping the spray and runnin a 200-250 shot on top of it. He was thinking of something in the 240-250's duration range and the 630-640 lift area. Also he would like to keep the lsa in the 110-112 range. Any help is appreciated.

Thanks.

I would talk with Livernois and see what they have to match their heads. You might follow this thread also to see how things turn out. https://ls1tech.com/forums/generation-iv-internal-engine/663004-out-box-vs-ported-l92s.html
