I know that forged pistons run more bore clearance than our stockers. TRW makes a std size forged piston. Are they slightly smaller in diameter to make up for the expansion, or does one just hone the bore to compensate?
The specifics: my preliminary inspection shows that my bore has .0005" total taper (difference in top and bottom diameters, not taper rate), and is up to .001" out of round. Std bore, still has crosshatch visible, along with some skirt scuffing. Would it even be an option for me to use th Std size TRWs with a hone to the .0045" clearance?
