We have a LS1 455 cu.in stroker. 4.186b X 4.125s
11.2 CR AFR 225 72 cc heads
Cam selection was a custom grind 248/252 .518/.625 112
Great idle with SD tune
Incredible power.
Car ran 10.92 @127 with street tires and closed exhaust, M6

Sounds like a strip car. Run a solid roller setup. 27X/27X 7XX/7XX

thanks alot for the replies, i will be using this car mostly on the street and some racing. how would this cam work out: 236-246-120 lifts at 0.625. this car is an M6 and i am planning on a 300hp shot.

Fair idle and max top-end power upstairs means an intake valve closing point 54-56 degrees ABDC at .050" and overlap under 25 degrees at .050".
You'd probably want something like a 246/258 114LSA +2. Lobe lift would depend on spring selection. This would have a docile idle. If you could live with a harder lope, more duration with a narrower LSA would work better. Something more like this would work better for a strip application: 256/262 111LSA +2.
