Turbo on my 350- how much boost...
I have a stock 350 bottom end, 4 inch bore, 3.48 inch stroke, cast pistons, powdered rods, cast crank. Motor with 76 cc heads stock was 8.5:1, with the 64 cc heads Im guessing 9.3:1 to 9.5:1. Wanting to put a Garrett GTA42 75 mm turbo on the beast. Ive been told to lock out my distributor, lower my timing to 28-32 degrees, use water/methanol injection, and 8 lbs of boost max or the engine will detonate and melt the pistons. Is all this info correct so far? Anybody got any useful tips or words of guidance? Thanks.
