how about ride height ? building the arrow count me in

I've never met Roy Hill personally, but I've seen him on TV and he reminds me of a drill sargeant in basic training. I suppose in some way that is what he is at driving school, but I think I'd try Frank Hawley first. Hopefully Roy doesn't make you do 100 pushups if you screw up?

So when & where is the first race? And what kind of car count do you have so far?

Here are the updated rules.

I'm jazzed about these rules! This is almost exactly the way I envisioned this class should be 3 years ago. I think most folks will be able to do this, without too much trouble. If ya afford to build this type/fast of car, I think this is a worthwhile goal to work towards. Let's face it, nothing looked cooler than the first 2 generations of prostock cars. I guess I'll have to get my butt in gear, and do the last few things to the barndoor..........

Looks good to me - remember, you can't please everyone. -- Reed in Neb.

Why the no tube car rule for class I? The tube chassis cars started coming out in 1972. You are eliminating a bunch of ERA correct cars, for example, the Roy Hill (ex Butch Leal) Duster you have pictured would not be allowed to compete.

We have the John Hagen Pro Stock Duster, the car is being restored right now out west to be identical as it was run in the mid 70's Lenco and all, and I am putting together an ERA correct destroked 396 Pro Stock Hemi to the core, right down to those ungodly heavy steel rods.

Need to say that the McCandless Demon is as correct as I've seen a Mopar Pro Stock resto, job well done.

What about '70-'72 Darts? I know there were a few in P/S during that time.

Also, Wedges are allowed correct? Whether it be big or small block?

I thought the Jenkins 73 Vega, was the first tube-chassis prostock car.

I never looked under the car myself, but I had thought the Jenkins 1972 Vega run at Pomona that year was the very first tube car. Jenkins is also credited with the first dry sump/strut in pro stock, but we have a dry sump system the was on one of the early Missle cars, just not sure which one? Our car was the very first out of the Don Ness Racecraft shop, and had/has a strut front end also.


The point is, there are many late 1972 to 1976 tube cars (Dusters/Darts) that are excluded in the rules as they are written, would be good to add the early tube cars to the Class II section as well.

As I recall, Jenkins '73 car would be considered a back-halved car in modern parlance, in that the front subframe was still there & converted to struts. Which leads to a question---- can such a car run N/PS and if so, is it a class I or II car?

BTW--ANYONE looking for a retiree (54 yrs young) to sign on as a crewmen? PM me PLEASE if you are.

I believe Jenkins 74 "Shovel nose" vega was his first McPhereson strut car, prior to that they were the conventional Back halved w conventional front UCA/LCA spring cars, I'm sure the original 72 car was (which I believe was the same car he ran in 73), 72 was all white and in 73 he added the candy red. 74 was the 'all new' car but by then the Gapp & Roush, Nicholson and Glidden 351C cars were already starting to become dominant in the Class.

IIRC the 73 weight breaks were 7 lb/ci Hemi, 6.5 Lb/CI Wedge and 6.75/ lb/ci for the Canted valve motors like the BBC and the 351C....Jekins saw he could get the rear weight distribution better with the strut suspension and when Mopar went to a destroked 396 and 366 Hemis the tube frame was really the only way to ge the weight down to competitive numbers. A little later they went to the over under 105" WB break which was aimed at making the Big Blocks more competitive again but unexpectedly brought in the G&R Maverick Taxi and later the 70 Mustangs of Nicholson and Glidden.
