Yep!
I wouldnt buy from them tho. Alot of supporting vendors here have done alot of testing with cams and heads and can build anything from a 346 to a 427+ as cost effective as an LS1 can be. A 224/581 cam with some Stage 2 custom ported AFR heads... the new 90mm LSX intake and full headers without cats on a m6 GTO it should hit 440RWHP and more with a bigger cam.
