Wow, this brings back memories. The L78 396 was a great motor. I remember, back in the day, this motor was looked down upon, because of the 427's and the 454's. This motor definately rocks. I had a 1970 SS396 Camaro with a muncie m21, 4.10 gears and no power steering. As a kid in high school, I raced it a lot. Only lost two races, one was to a 1969 L88 Corvette and second was to a 1969 Plymouth GTX 440 six pack. Of course back then the 5 mpg I would get out of it was not so bad at 39 cents per gallon of 103 pump octane.
