For sale is my freshly machined and very rare Pontiac 421s/d 4" stroke 3.25 main forged crank with torque tube provisions (transaxle cars). It will come with both the Clevite main and rod bearings (I believe .202/.020). I was building a new 428 last year with it when I discovered the pistons were too far in the hole (old Venolia blower pistons) for a n/a application. The crank was fully inspected and checked for cracks with none (crank had very little use). $1400 with the bearings plus shipping. NO TRADES. Thanks for looking.

Sorry for the question, i am not a buyer for the crank but have never heard of "torque tube provision" what is that?

I believe for an adapter flange to bolt to end of crank for a rope shaft car

Sorry Nate, I sold it to a gentleman last summer that needs it for a transaxle build. He did have a fresh 990 crank w/o the ropeshaft provisions, I can see if I can find his contact info if that will help you. I do have three nodular 428 3.25 main cranks, one of them is fresh index ground.
