1962 421SD Pistons
 
Any of you Pontiac guys know of anybody who might have at least one decent 1962 421SD factory piston ?

A Stock racer needs one to send to the piston maker to duplicate & send to NHRA for approval.

I have a set of original 455 SD pistons if that will help.

Mickey Thompson ORIGINALLY made the "custom" pistons for the SD engines might try contacting M/T see if they still have any prints and /or they would even make 1 piston OR if they had any paperwork where they could still make a piston---FED 387

Thanks for the replies !

I'll check out all leads.

I know there are bound to be a few guys who have gathered up lots of the old 421SD stuff. I just don't know any of 'em.

Don't need a whole set. Just need one decent piston, suitable as a pattern for making a copy of it.

But, I suppose an official, detailed description MIGHT be sufficient to get NHRA approval. Or, must they see an actual original piston, to compare it to the copy ? Anybody know, for sure ? :confused:

Yeah, and the guys who are gonna do it know what they're doin, too ! :)

Back in the old days, before he moved on to quicker stuff, Don Gay did pretty good with a 421SD Stocker. I suspect these cars won quite a few races around the country, on thru the mid '60's. I don't have a clue how long it's been since anybody had a serious 421SD Stocker. ??? But it's been long enuff so that there are no NHRA approved pistons for that engine.

Love it. Well, while I'm being ignored let me chime in with some facts. Pontiac had their own pistons too, not just M/T's. I've had three NOS sets given to me by Jess Tyree when he was running my engine in his '63 Tempest. I still have one full set.In the factory boxes with factory part numbers. But that's ok. Pontiac knowledge? Who? Me? pfffft.
