i baught an engine that was said to be a 94 camaro LT1 pullout...
while looking on the net for torque specs, i found out that they are 2 bolt main blocks. the one i have is a 4 bolt main block.
does anyone have info for block identification...
some say this is a corvette LTx block.
i want to replace the mains/rods bearings, and the ones in the engine now are thicker for the mains... the stamp says .0006 is this 6 thousands oversize...
need bearing to crank tollerances too.

does it say 327 on it? Thats how you tell if it even a Lt1

Look for "327" by the motor mount on the block

4 bolt main doesn't necessarily mean LT4 block, just means it was out of a Vette or could have been a replacement motor. They are the same block anyway.
