Cheapest 4" crank?
#5
Since Eagle can do a cast steel stroker SBC crank for under $200, there's no reason they shouldn't do the same for the LS for under $500. I've had a supercharged 383 hit 640 HP at 6000 rpm with a $250 (new) cast steel Scat stroker crank, a 350 SBC stroked to 383. Cast steel will more than suffice for a <500 hp LS.

The Callies C-Series stuff is probably your best bet.

Yes it should be fine Jim. For extreme NA or high rpm or power adder use I would use the regular 4340 crank but these should work fine on an NA normal hydraulic roller engine.
