Just got it started and running this evening before the sun went down, its got some noticeable cold piston slap now since i honed the block when you rev it, but it seems to settle once its warmed up, although i think this is normal with forged pistons. Off to tuning developements Thursday morning AGAIN! i am a bit paranoid about driving the car there and back, i might trailer it, what do you think. I have got to run the piston rings in tomorrow just before i go, talking about a tight deadline!!
