Hey Probert, Is the motor a chevy or a pontiac? Also the Saginaw is probably a 3.00 first gear. A lot of torque especially is it is a Pontiac motor. sam
[/ QUOTE ]Definitely a Chevy with the head castings he listed. Unless someone did some serious work on it.
As everyone else said, those are great heads and shouldn't be a hinderence for building a nice streetable small block.
