Manufactured by Cola for GMPP.

3.8' stroke 4340 forged, 1pc RMS, perfect shape. Only out of the box to look at.

I bought this crank for use in an LT1 but found out that it will only work in post 1986 NON LT1 applications IE L98 or vortec engines. It requires a 400 style weighted damper and a neutral flywheel/flex plate and will not work with an LT1 damper.

Let me state that this crank will not work in an LT1 without adding mallory to get it to balance or the use of a wieghted SBC 400 style damper.

Thanks for looking.
