Going strictly from memory, Don's second picture looks correct for a '68. One of our local guys had a white '68 Malibu L-79 4 speed car. I was surprised when I finally got a peek under the hood. I was expecting the Alum. intake, a Holley and the Chrome accessories like I had seen on the '65 Chevelles and the '66 & 7 Novas. Still, a pretty stout small block.
Who's our L-79 expert? Jeff Latondress, where are you?
