L72 `69 Camaro NHRA stockers

[larry_csa]

The set up your are asking about is a E or F car, depending on weight. I have a 396/375 steel and alum head motors. There are not many 396/350 cars out there. NHRA just took some HP of this combo to get more of them out there. I would think that they should run about 1.50 in 60. If you want to discuss A B & C cars we can talk.

Larry a L-72 is a 427-425 they run B or C stock The 396 -350 can only run F/S in a Chevelle I think. We run a B/S Nova 396-375. Short times are best of 1.32 to 1.46 Fastest time in 1/4 10.32 Kim

Kim:

You talkin' Chevelles or Camaros? DeArmond was the first "stock" car in the 9s in his L72 Camaro in A/SA trim, and Sorensen recently went 9.97 at Woodburn as well.

I may be reading too much into it, but it sounds to me like Eric hollered at Larry offline asking about a different combo, and that's where the E-F/S talk came in. [img]/ubbthreads/images/graemlins/dunno.gif[/img]

Rob they probably talked off line I was commenting on L-72 Camaros as far as class they ran in [img]/ubbthreads/images/graemlins/beers.gif[/img]

[Chevy454]

Gotcha. What kind of MPH does that B/S Nova run?

[Kim_Howie]

Rob, I think times 127 128? [img]/ubbthreads/images/graemlins/beers.gif[/img]

Thanks for the replies [img]/ubbthreads/images/graemlins/smile.gif[/img]

I was under the impression the 427/425 Camaros ran A or B Stock. Am I correct that they run un-factored at 425 hp?

Re: minimum weights...

Stick car is natural A/Stock at 8.00 lbs per HP. Add 170/driver = 3290 min.
Auto car is natural B/Stock at 8.5 per HP. Plus 170 = 3485

Is this correct? As I'm predominantly a "street car" guy, the whole NHRA factoring thing is a little fuzzy to me, hence the "newbie" questions.

I would like to discuss this further off the board if anyone is willing to share some info. I obviously don't expect anything proprietary, I'd just like to cover some basics to make sure I understand them correctly. If anyone is willing to help, please PM me or shoot me an email (in my profile). Just trying to spare a little board space and bandwidth [img]/ubbthreads/images/graemlins/beers.gif[/img]

Might as well cover this here, in case anyone else is interested. The rest of you class racers jump in and correct me if I lead him astray...

First off, take a look at the NHRA Stock Car Classification Guide. This will provide you with the current HP factor, from which you can figure your minimum weight and your class. I'll use the L-72/400th as our example.

From the link above I select "Chevrolet, 1969", which will open the page for all 1969 Chevrolet combos. Then, I scroll down to "Camaro", to "Coupe w/TH", which is the L-72/auto combo. It tells me it has an "8.06 lb per HP" factor, and is factored at 425hp. Now, with that, I look in my NHRA rule book (thanks Barry!) and it tells me that it falls in "A-stock", which is 8.00-8.49. Now I can figure my minimum weight. Since it's a natural A/S car, I can use the class minimum weight factor of 8.00. Multiply 8.0 by the Hp factor (425), add 170 for driver, and you get a minimum weight of 3570. NHRA also allows you to drop down 1 class by adding weight, which means since it's a natural "A" car it can drop to "B" by adding 212.5 pounds.

See, clear as mud! [img]/ubbthreads/images/graemlins/grin.gif[/img]

First I'am sorry for the mistake of misreading L-72. I should not answer the computer at 11.30 at night.
NOW. A 427/425 will make A only in a 1969 camaro. It can not get heavy enough to go to B.
Fast A cars Bobby D.
Bobby Brannon
Thomas Arnett
Joe Sorenson
A 1969 CAMARO will make B with a Stick but will NOT make C with a stick. It will not make weight.
Fast B Stick ED Bendez
Geroge Cottell
A 1969 CAMARO will make A OR B Stick with Alum Heads.
Fast A Stick Kevin Helms
A 1969 CAMARO will make B or C Auto With Steel heads.
It ONLY make B with Alum Heads.
A 1969 CAMARO will make E auto with a 396/350 Motor(parson & Myers)
I do not know anything about weight for Novas or Chevells. the Person asked about A CAMARO. I run Div 2 3 & 4
