----Freddie,,,Im sort of with you on the MPH claims, but did you note the non-original rear end gear?......Bill S

Cliff's a legend - look him up. How many teenagers managed to get through the back door at Chevrolet and get cozy enough with Piggins, Zora and Ed Cole to score a Z16 and then an L88 Corvette to race with under the table factory backing? Exactly one: Cliff. His life is the stuff of movies.

Anyone that hasn't read the story about Cliff building the L88 Corvette and driving it from Kansas to Daytona and back needs to look it up, absolutely amazing story!

I thought 3.31 was the factory ratio for the Z16. Did I miss something?

This looks like the car Patrick Nichols did a video on.

----This Z16 was, I'm pretty sure, given to Cliff to evaluate and evaluate it he did. I'm not sure weather he installed the tall gears or weather GM installedthem for him to do the top end run!.......Bill S

That's also always been my thought as well. As far as the MPH claim, I kind of doubt it. Even with that gear, and a 26" tire, it would require you to spin about 7400 rpm to reach that speed. Quite a feat for a stock hydraulic cam.

Problem with that is not only the engine appearing to be stock in the photo's complete with exhaust manifolds, I doubt the engine would make enough HP to overcome the aerodynamic challenges involved to reach a speed like that.

Unless we aren't getting the whole story?

Neat car though.

I know what my 69 turns with an M21 and 3.31 gears at 72 mph. I know it's not a Z16, but 172? Ha. Not without some mods like has been mentioned.

A friend of mine had one of these cars and he took me for a ride. He had 3:08 gears in the car. He said "you know, these can peg the speedometer! I said really! He said that the speedometer starts bouncing pretty bad at about 130, but with a 27 inch tire and the 3:08 gears you watch the tachometer. When it hits 6100 rpm you are pretty close. Then he looked at me, smiled and dumped the clutch. The speedometer was pegged and so was the tach. I don't know if we were doing 160 or not but I'll bet we were pretty darn close. All of this on bias ply tires!

That story about Cliff Gotlobb was awesome. Wow, what a talented individual he must be/have been to have Chevrolet pull him in and take his ideas into production. Really cool.
