I have recently acquired a 396 and i'm trying to figure out which one i have.
The block# is 3916323 head#3917215,and this number is on the fornt of the blk(T1213ef). Any information would be greatly appreciated. Thanks in advance.

1968 396/350hp originally mated to a manual transmission.

LS6 thanks for your quick reply. Motor runs good taken in consideration it's been sitting for almost 21years. Found it in a 64 el camino the only thing I did to it was normal tune up,new carb and fuel pump. Thanks again.
