010 Block

[BBIGG BLOCK 396]

I just aquiried a smallblock 010 4 bolt main block,looking up the 010 numbers it says a 302 or it can be a 350,how do you tell if it is a 302 block for a z28 Camaro or a 350 block!

Thanks

It was used in both the 302 CID & 350 CID engines.
1969 was the only year it would have been used as a 302 CID for the Z/28,so check the casting date in back & application prefix stamped on the front pad,and if there's a VIN# stamped into it too.

A cast date of April 69 to November 69 could be 302.

I thought it was the crank that made it a 302

what are the #'s on the front pad, this wil tell you if it came out of a z28

010 is the last of the '69-'70 Z/28 blocks (302-350)and was commonly the replacement or "service" block that was used.

Sure, lay the pad numebrs out. . Any crank w/ it....and if so, is there a pie shaped piece out of the flywheel end? ~ Pete
