School me on SS427s!

As for the L-72 I have read it was suppose to happen but never did no car has ever been found or paper work to support it. There was a Tripower set up that was also going to be available and when the vette boys heard about it they put the kabash on it .. They only wanted tripowers on there precious corvette .. The engine is in the build manual with a cancelled stamp on it .. it did not denote as L-72 I believe it was L-68 I found this.

And from everything I have read and seen RPO F41 is heavy duty front and rear susp. You could order this on almost any car if you wanted it just like ordering the 427 in a Biscayne in 67. This one is an original restored White with green guts,,

It was just a random owners manual I decided to page through one day. I assume that picture is in all editions.

I always understood that F40 was the heavy duty suspension, and F41 was more of a sport suspension, because it had the sway bars. I don't have any of my literature handy right now though.

------Paul,,,L68 in the 67 Corvette world is the 400hp upgrade on the 390hp motor. That would have been an interesting combo in a big body. Tons of torque!!! The comments on 427/425 Vettes are on the mark in reference to acceleration, but I can tell you that I have driven many 66 427/390 Vettes that could stay up with all but the best tuned 425s. I think it revolves around the somewhat temperamental attitude of a 425, and the abundant torque down low of a 390..........Bill S

Remember the thread here a couple years back where someone very reputable laid the story on us of his long gone '67 L72 B-Body...GM factory demo maybe?.
The thread included pics of a tag he'd saved that was an additional tag (perhaps inner fender mounted) that had 'Special' or something to that effect on it?.
There's been a few other '67 L72 B-Body reports that sounded to be possible truths over the years but this was the one I had the most faith in..

That's it!.


Thanks Rick, I'd forgotten it was John Z just remembered it was someone reputable..

Among other reported factory '67 B-Body L72 cars I've heard of are a few Canadian cars including Canadian Pontiacs..
As many here are aware, Canadian B-Body Pontiacs had Chevrolet chassis and drivetrains..

The twist to keep in mind w/ this is many (but not all) Canadian built Chevrolet powered Ponchos and Chevys had unique suffix codes that had alpha/numerical digits and included in these were the Tonawanda built MK1V's..
What I'm getting at is an unknown '67 B-Body L72 suffix for Canadian production is a very real possibility too!.
