This is IRT the crank grinding question
Just like anything involved with horsepower, it depends
on how much money you have. I know the 1600/2000
stroker will live quite happily with .040 overbore, I would
think this would be the road to go before
fooling with the crank. I will have to get
the formulas out to find out how much
this gives, but would SWAG it at
2100 or therabouts on a 2000 stroker.
Plus, bigger piston
squishing same combustion chamber means
higher compression.

SWAG equals
