SB Engine ID???

[James W.]

I have this Chevrolet SB engine and I'm trying to identify it. The casting numbers are 3944660, the numbers on the stamp pad are 180123 31 T1023HJ and the heads are 464 castings. Any help would be greatly appreciated.

Thanks,

James West

I believe the block casting number is 3914660, this would be a 1968 327ci engine, 250 hp, powerglide with 4 barrel in a passenger car. This is according to "Chevrolet by the Numbers". The head casting needs to be looked at a little closer also. I find no such casting number. There are several places on the internet that list these numbers. Go to any search engine and type in "Chevrolet Head Casting Numbers" Hope this helps
