Re: What should piston to wall clearance be
The ring gap was fine, no sign of butting. The manufacturer originally said to run .0055 clearance. after seeing the pistons they said I should run .0075.

GPM is that what your running now? (0075). Do you run at high rpms for extended periods of time? (Lots of heat) Are you supercharged? Thanks Greg

Re: What should piston to wall clearance be
I would like a cat. I was thinking about an Eliminator 28 single. Whose do you have? Are you running an m-1 m-3 m-4? I have an M-4 and only ran it 1 time. Then boom. I used to have an M1 for 4 seasons. I think I had junk stuck in the oil cooler impeding flow to the motor. Maybe bad gas. Oh well gonna play! Greg

Re: What should piston to wall clearance be
yes I agree. I am thinking I will put this setup on the dyno before installing in the boat and watching the fuel pressure and egts etc. What kind of boost are you running? can you get 115 out of it? Greg
