Here’s another project I’m finishing up. It’s an 08 Yukon Denali that had a 6.2 L92 in it. I built a 418” L92 with ported heads, GPI SS1 VVT camshaft, Molnar crank, Molnar power adder rods, Racetech pistons, 1-7/8”x3” headers, 2800 stall, built 6L80E. Had issues right after I installed the engine and took forever to figure out the ECU was bad, wouldn’t ground 3 injectors. Tossed a new one in and hear this right away!!
