Harmonic Balancer / Crank bolt

[john108]

On Summit website they have the "Crank Bolt Package 2.25" Bolt Heavy Duty BBM/Hemi"

Thread Size:3/4-16 in.
Underhead Length (in):2.250 in

When I disassembled a 440 engine to remove the Block, the Crank Bolt I remover only measured 1.25 in Length.

What is Correct?

I will be using the Summit Harmonic Balancer SUM-163383
Harmonic Balancer, OEM, Internal Balance, Nodular Iron, Natural, Chrysler, 383, 400, 440, Set.
AND CCA-3125, Timing Chain and Gear Set, Comp Cams

Picture of engine that was dis-assembled for block is attached.

I'm not sure, but you can save a buck by re-using the existing one. It is probably the most overbuilt, indestructible part of the engine and should last forever.
