Re: Tight Piston Clearance, Not Model A
We always used about .001/inch for cast pistons. Kieth Black's can run a little tighter, especially in aluminum blocks. Forged pistons got about .0015/in when I did them many years ago in race engines. What we did then was crude compared to what is done today. Ron W
