CCW cranks won’t “jump rope” or flex in the center at high rpm (7500+) like a non-CCW will. Bearings will tell the tale. But…the OEM LS/LT blocks aren’t machined for the CCW cranks. There was a thread here once upon a time talking about CCW cranks in an OEM block. Unless there’s a heavy filet in the CCW counterweights to clear the center Oem webbing, the CCW crank won’t work.

I’ve never seen Callie’s info on the fitment of the CCW cranks, but I’ve seen other manufactures of CCW cranks that specifically say they won’t fit an OEM block.

From the way I read his post no clearancing is required. The center counterweights are tapered and miss the bulkhead by .060" - .065" so it is a drop-in affair.
*As noted previously my Dart crank required minimal clearancing but it has full profile center counterweights*....

Because
"The (blocks) that need clearancing can be done in about 30min on the mill. Not a big deal at all."
"I have done it on a 6.0L with a 4.00 Dart billet CCW crank."
