stroker engine balancing

the rod weight is a big factor in determining (and getting) a light bob weight. So as long as you have light weight pistons and a decent set of rods it should not be too hard to get an internal balanced forged crank assembly.
with a 3.79 stroke, Eagle I-beam rods and Diamond forged pistons my 388ci came to 1826gms bob weight - and lots of metal removed from the crank counterweights to balance.
