63-66 Pontiac N 421 crank 9770488
 

Was told this was nos when previous owner got it many years ago with some Trophy 389 parts. it is def standard standard and shows no signs of being in an engine. 4" stroke, 3.25" mains, 2.25" Pontiac rod journal n crank. My assumption is this was a later parts run as the part number is partially hand stamped.
Needs a polish but was stored in a dry basement. This will
Fit in any 421/428/455 block. Crank about is 1/2" shorter but the balancer registers on the crank gear. Match your timing cover to your balancer and everything works. Pics
