I guess i should update this a bit, February of last year the bolts on the cam sprocket backed out from not having any Loctite on them. fixed that issue and have been driving it till today, when it locked up, not blaming the engine builder but I do not think I will be using him again. I'm about tired of working on this turd. its probably gonna get an iron block 6.0 with the original ls2 rotating assembly and a cam, unless I just decide to sell it as is.
