block isn't any different physically than a street hemi - they key is the numbers on the pad by the distributor.

Lots of guys say they have a super stock block but few do.

Post the info here if you want or look for HC (high compression) on that pad.

yep the "HC" is the key from a street hemi to a race hemi...

i think there was another stamp that helped identify them but dont remember... my boss would know
