Re: How to recognize a L78

L78 has aluminum intake, square port heads (quickly identified by the height of the intake runners on the head as we as the small half round casting mark at the parting line visible on the face of the head), Holley carb vs Quadrajet, 837 alternator vs 834, different distributor just to name a few. Besides the fact that it is cast iron, you can clearly see the individual intake runners are not as tall as they are on a square port intake.
