Hey John,Rick,
it is simple math, the block is 11.500 tall in stock form.
crank stroke, 4.25/2 =2.125
rod centers 7.500
11.500-2.125-7.500 = 1.875 CH of piston.
These are basic dims to work from, flatheads are generally not that tough to do, adding pop-ups to overheads can get interesting.
John
'SIMPLE' to you
Coincidentally, with this morning coffee, watched a news segment the subject of which was ....is math still needed/useful in school
I copy your formula, thanks much.
Now , tell me how to calculate the amount of popup pistons for my Schofield head use (3/4" comp chambers) ?
