I just found out that due to me taking it to the place (not going to mention this company's name) to get my dyno, the maxed itout so much that the head gasket blew. The motor is apart right now. I have the heads going to get milled. Not too bad but don't wanna take any chances. This engine comes with ported heads, yellow crane rockers, bosch 42 lb injectors, ported intake manifold, forged pistons...etc. I will not put this back together. I want the ls1 and will either part this motor out or just have someone pay enough and come get all of it.
