Does anyone know the diff between 3LN3 and 3LN6 pistons (p/n 3ln-11631 has suffixes -01 and -02)? I can't measure any, and having no idea how to get the gudgeon pin clips out, would like to leave the 3LN3 bottom end when I drop the LN6 head on.
Nice article on EngineBuilderMag about bearings, clearances and honing. https://www.enginebuildermag.com/20..._campaign=Tight+Tolerances+and+Building+Power
That's a great article. In case anyone is wondering, they show a picture of two guys and mention one of them is Greg Anderson. The below pic points out which one he is. You can use the following link to appreciate what Greg knows about engines. Greg has won 3 Pro stock championships as a crew chief and 5 as a driver. Good post Blair. https://www.nhra.com/drivers/greg-anderson/871
