    Asked by: Jerseyboy
    The engine block that we use for this build is a brand new factory LS3 engine block, when we build this short block up we normally use our LS3 L92 (PS8015) cylinder heads to complete the build.

    The piston that we are currently using in this engine build is a 8cc dish piston. This engine will be right at 11:1 with a 70cc LS3 cylinder head.

    Does this come with a cam, lifters and rockers, like the description says as the picture appears to not have a cam in it?

    Asked by: KC87
    This short block would be a block, crank, rods and pistons. The description on the website says that it includes a 58x reluctor but does not include harmonic balancer, cylinder heads, induction system, camshaft, lifters, oil pan or flexplate.
