Has anyone ever machined a dish in a stock piston?
I'm doing a head swap and don't have the time to build up a new short block. The heads are ported GT40p with 56.5cc chambers. I have a low mileage stock short block that I'll throw them on. However, I'd like to stay under 9.5:1 compression due to a lack of premium gas around here.
Is it possible to turn a stock piston with the 5.5cc valve notches into a +10cc piston?
It might be just as cheap to get a set of KB Hyper +11cc pistons, but I thought I'd investigate.
