Casting Codes:
Con 3
G131
3788378
According to the charts I have cross referenced, the block is a 292 but it is clearly not unless Chevy casted 292's with the shorter side covers. Anyone have any insight here?
Thanks,

Can't be a 292 if it's got short lifter panels. Could the casting number be misread? A 373xxxx casting would be in the 235/261 cubic inch series. Obsolete after MY 1963.
I know some racers built "Cheater 292s'' with a bigger crank and pistons in a short 230/250 block to get around racing inspectors, but GM never did that.
This is kind of a Zombie thread that keeps popping up every 3 or 4 years.
Show us a pic of that block, if you're indeed not one of the ''Undead''.
