340 Crankshaft bit the dust
Most were not hardened
and factory cranks had high pressure rolled filets not big radius
the pressure compresses the metal down giving an excellent crank without the need for chamfering the bearings or grinding away the filet with a regrind
not to worry
works good
hmmmm use chevy bearings and adjust the stroke,
chevy size rods are easier to clear with big strokers
for whoever posted above
the 340 pistons to start with on that build are the low compression ones
you can also mill half off and try and get some quench
watch your PV clerance
