Ok All,

How much power can the 3800 make over stock without pulling the valve covers?

So going by the stock horsepower of 200 hp.

How much power with injectors, a tune and headers? Does anyone know?

My son has my old 2000 Park Ave Ultra with a mild ported M90. Not abused car, but the dreaded forward apply band in the 4T65E broke, so it doesn't drive. He needs to part ways with it.

Make him an offer. Engine runs good, I put a LS6 MAF on also. If anything top swap, but the whole engine is very solid. I bought it at 67k and its at 220k now. Well cared for, but the transmission needs the forward apply band replaced.

Its in Peoria, IL.
