The original owner was a stickler for keeping records. The car originally came with a muncie shifter. Car was purshased Oct. 2 1970, and on Oct 13 1970, I have the bill from a speed shop where he purshased a Hurst shifter and installed it. That's interesting that this car came with the Muncie shifter and the Yenko's got the Hurst. I was thinking this had to do somthing with the order form and was also why the Yenko's came with M21 and the Canadian COPO's got the M20.
Marlin is correct, Central did originally order 10 of these cars but for some reason, Chev would only ship two. Original salesman confirms this, but does not know why!

Pete, Does your Nova have the rear sway bar? I wonder if the Hurst has something to do with Yenko's 9737 COPO number.

Interesting stuff guys !!!

The 3412 is kinda interesting for my car too. Mine weighed in at 3636 in Stanton, with my 165# lard-ass in the seat. That puts the car at right around 3471. Not bad ........

Joe: Yes the car came with and still has the rear sway bar.
Peter
Also the number on my GM micro film shows 9010 BE and 9737AA. Is there a different version of the 9737 as in 9737BA? or something like that???

Pete;
I will check my copy of Yenko's order form to GM for the Yenko Deuces, he listed both COPO's on the form but I don't remember if he listed the suffix letters.

OK, I did some snooping around on the NHRA website (just for kicks) and here is what I found. [Note: the info below is for STOCK classifications]

For the Nova, the highest factory HP 350 they have listed is the 300hp, and the NHRA factored it at 290hp, and 11.09 pounds per horsepower. They did list the Z/28 Camaro, which had the identical engine as the COPO Novas, and it was rated at 355hp (360 factory hp) and 9.41/9.57 (4-speed and auto) pounds per horsepower. The Corvette incidently came with a 355hp factored from the NHRA (370hp from the factory) and an 8.89 pounds per horsepower factor. But, they also listed a 350 Corvette with a factory 350hp rating that carried an NHRA factored 370hp, and an 8.65 pounds per horsepower.

So, if you take the numbersfrom the 300hp/350 Nova, and multiply them you get 3213 pounds. Then, if you divide that number by the NHRA factored HP for the LT-1 (355) you get 9.05 pounds per horsepower.

I checked the Olds for Casey while I was there, and here is what it showed. The F-85 carried a 350/325hp rating from the factory, and also had the same 325hp rating from the NHRA, and 10.5 pounds per horsepower for a weight of 3412.5 pounds.

Now, I know NHRA has played with the factoring numbers numerous times over the years, so this is a very rough comparison. But, it's interesting to read!

There was a post on the CorvetteForum board recently where someone found an NHRA rulebook from 1972 and posted the factored horsepower for Corvette engines. The 1970 LT-1 Corvette engine (350/370) was factored to 400 horsepower (for the 1972 racing season at least).

http://forums.corvetteforum.com/zerothread?id=194037

The 355 horsepower figure seems awfully low for a 1970 LT-1... Misprint maybe?

Regards,

Stan Falenski

Stan:

This is the current NHRA rating of the LT-1. It lists the 355hp rating for the Corvette and the Camaro, in more than 1 place, so it doesn't look to be a misprint.

Now, as it turns out, I was over at the Super Stock site in the chat room, and was asking about what class the Nova might have been in. A couple of them mentioned that they new of a Camaro or 2, running the LT-1s, and they weren't too impressed with the combo. Said that it wasn't under the index, so they were curious about the Nova as well.

As best as I can tell, the NHRA ratings have fallen over the years. Remember, it was NHRA who rated the L-72 at 450hp for a while, but now it's down to 425hp. We've got several old NHRA rule books somewhere, so I will see if I can dig them out and see what's in them.

The NHRA site has some really interesting stuff on it, and is worth the time to dig for the info.

[Note: when looking for info, make sure which specs you are getting. The NHRA posts both "Stock" and "SuperStock" ratings/factors, and they are VERY different!]
