- I am looking to stroke an inline Ford 6 cylinder. A friend once used chevy rods in a 240 to DE-STROKE it for higher RPM's.
Is there a way to determine the best rod length/piston pin position/stroke, to achieve maximum RPM without too much cylinder wall stress? Looking from the crank end as it rotates, it appears as it reaches maximum outboard swing, it causes stress on the cylinder wall as the piston starts up the cylinder. I want to find best rod length when stroking an engine, to achieve max RPM without too much stress on cylinder walls. For now I am simply looking at theory and possible over-the-counter parts options. Throwing things out of balance and throwing pistons through the block are my main concerns.
