Cliff,
Thanks for the warning on the later shafts I went back and looked and this one is a 1967 Armasteel crankshaft is 9788787 if it makes a difference in your selection. Magged and turned 10/10. as is the 4.21 just thinking the 4.00 would not be as explosive on the lower end torque and more on the mid-upper range.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
