Ok, as many of you may know, I've been building my GP. Here's what's done...L36 block, Gen V, IC'ed, XP cam, stock lifters, HS 1.6 roller rockers, JP single roller timing chain, 42.5 lb injectors, PRJ fuel rails, Fuelab FPR, SLP headers, GMPP exhaust, Getrag 284 5-speed. Finally got up the gusto to fire it up last night. Lifter noise...normal if they pump down. Oil Pressure stayed around 50 lbs. A/F in the 12's at idle due to no tune.
This morning...flashed my tune into it. Car started, lifter noise stopped, and the engine stalled. Will not restart. Low compression, engine cranks over quickly. Removed spark plugs. Dry. Removed rocker cover to check to see if lifters pumped up and stuck valves open. Nope. Removed timing cover. Engine is perfectly in time.
What am I missing? I can't see why this thing would lose compression after the lifter pumped up unless they stuck a valve open. If there were cylinder washdown from fuel, my plugs would be wet. I'm tired and I need some help.
