Hello All,
Well I have successfully turbocharged an inline 250 in my 1966 GMC SWB pickup. It runs really good and will fry the tires. I also just installed a WC T5 5 speed because I blew up the 3 speed. I am running the factory intake and exhaust manifold with a GN T3 turbo, Holley (hanger18 mod) 350cfm carb, factory points conversion ignition. It starts right up and my boost is set to 10psi.
I feel the engine is worn out. I realized this before I started, mileage unknown. I am getting blow-by from the boost causing oil to shoot out of my oil pan. I believe worn rings
I want to rebuild the engine this winter. My question?
How should I rebuild it? stock specs?, possibly forged pistons?, better head gasket? Different cam?
Would I benefit by running a OFFY intake?
Would you get a HEI and lock it out?
I wanted your opinion.
Thanks,
Shad in Nashville
