I finished the engine with Edelbrock ETec 170 heads, Summit Pro SBC Billet Stage 2 cam 8801, Comp Cams Magnum 1.6 roller tip rockers, Cloys single roller timing set, Holley aluminum chain cover with the crank hole which seems to be a lot better than the stock plastic, new GM balancer, all the Vortec stuff off the old motor with new MPFI spider, NGK BKR6E-11 plugs, Summit 8mm spiro wires, Summit Vortec distributer with brass terminals. I am fighting a random missfire issue. I believe it is going to end up being the stock PCM, because I still need to do a 0411 swap so we can plug HP Tuners in. About to put mid length headers, true 2.5" duals with no cat into a Jones Full Bore dual in dual out crossflow muffler.
