The L79 in the 67 & 68 corvette had an aluminum intake and was rated at 350hp. In 69 the L79 was no longer available but the equivalent was the 350-350hp which had a cast iron intake and rochester carb.

The original version started out with the aluminum intake and small Holley carb. (350hp rating) In 1967 the L79 was changed to a cast iron intake and Rochester QJ....HP rating was dropped to 325hp. The rest of the engine internals were the same...cam, heads, 11 to 1 pistons, etc. The only thing I'm not sure of is how this engine was setup for the Corvette in the 67-68 era...but for the Nova and Chevelle the info above applies.
