Alright, I have a 350HO 350 from GM, it puts out 330 hp. It is in my 88K5 with stock throttle body and stock computer. I had a knock going on in it. I pulled one of the heads off, and pulled all 4 pistons out. On 2 of them I had broken a small piece off the side of the pistons, towards the top, which had scratched the piston some, and the cylinder some, but nothing too bad. All 4 of them were burnt fairly bad on the top too. Guy at GM dealer said that b/c I am running that engine with the stock computer, the cam is confusing it and thats messing it up and that's what caused the pistons to heat up so much and break the piece off. So he said I have to get a new chip burnt. Here is how everything adds up: (keep in mind this is a $2200 engine from the start) Option 1 8 pistons, $300 machine work $250 rings and bearings $150 new custom chip burnt $400 total $1100 Option 2 stock 350 $1600 with 3 yr parts and labor warranty, no computer mods. minus a little b/c I can sell what I have right now Option 3 buy 383 kit from summit for $1100 have machine work done $250 new chip $400 total $1750 minus a little b/c I can sell the crank and maybe rods I have right now If you were in my shoes, which option would you take? I am leaning towards fixing what I have just because it is cheaper, and I don’t have much money right now. But I just wanted a couple of other opinions. Thanks!
