3.58 stroke x 340 main (rods/pistons?)
I built a stroker 340 with a 4" scat cast crank.
I used the light kb416 .040.
hypereutectic pistons and the summit (scat) rods.
I paid $400 for balancing and $350 for the heavy metal.
If I was to do it again, or advise, I would have bought a balanced kit with the forged crankshaft
