Found a 64 Nascar Hemi Block

what makes it an Nascar block?

So far NOTHING. Still have to see what, if anything, is stamped on the pad by the distributor. It could be a drag racing block.... (?????)

Obviously, it's not a production piece!

Why is it not a production piece?
 
The engine is with a guy I know that has just had a heart attack. Prudence is that I will wait until he is better to proceed with pics.
 
If it is or was a NASCAR block would ot not be registered with NASCAR?

It would have nothing to do with Nascar. They did not record what number block was in what car back then.
Do they do that today??

By "Production", I mean the engines that were produced for street driven cars, starting in the 1966 model year to 1971.

Getting the guy back on his feet supersedes some old iron block....
Thanks for the update and I wish your buddy well in his recovery.

Oh yeah, I forgot about that, thanks.
 
No body answered The question, what makes it an nascar block? I don't care if the block in question is one or not I just want to know what makes it an nascar block?

It is a race hemi block, by casting date. No street hemis till 66.
Afaik, the only thing making it a nascar block would be installing it in a nascar car. Race hemis were in package drag cars in 64 and 65, and over the counter ( or out the back door) for the nascar builders.
 
To my understanding there where no race hemi's sold in vehicles titled for road use or with factory warranty.

I think you'll find that there were a few. A friend had a real 64 Belvedere hemi H/T auto (steel car , no aluminum, no scoop) whether it was titled for street use originally I cant say. But it was when he owned it.

Certain numbers on the dist. pad will let us all know if it was for Nascar or drag racing.
 
I know Chrysler did their testing. But just can not believe they did not keep track of where these engines and blocks went when going out the door. Especially until 66 when the street hemi was available to the public.

They did keep track.
I have some info, but it's from the late 60s, so it won't help in this case.
That being said, there are numbers that will reveal if it's a drag or circle track block.
