Welp, it's fixed. Did a mild rebuild on the 6.2....new cam bearings, lifters/trays, honed cylinders and new gapped rings, LS3 cam, LSA intake valves, and thicker cometic gaskets to bring compression down to around 9.5. Between 6-7psi now but blows the tires right off from idle. How it should be!
Random pic for info...the difference between L92 and LSA intake valves. LSAs are a bit heavier duty. And only like $3 each.
