Re: Bring back super/mod...
 

Any of that could work, but way more back-half cars available, then legal stockers. Would put most behind already. What I think they want, is to regain the popularity of super-mod. Which involved back-half, and scoops. But no rules committe will please all. The ones who want to run no-breakout will enter, the ones who don't, won't. Could also let any year car in, and give a 75lb. break to cars older then a certain year. The $500 dollar head switch would be a $ saver. Lets say first place car draws a number out of a hat, and exchanges. We all know most dollars are spent on heads, and that would keep anyone from trying anything illegal. At least it works for me.

Re: Bring back super/mod...
 

I started out racing my camaro as a c/sm. That was a tough class to cut your teeth. It was several years before I could run the index. Running the 10.5 tire was tough back then. Clutches were real heavy. I could lay black marks in 3rd gear. The light cars with the small engines were best for the class. My car was not real light so I had to use a 305 Cu In engine. The chevy II cars were better for the class because of lighter weight. There were several guys that were real fast. They were cheating up the cylinder heads similar to the acid SS heads in the day.
The engines made good power but the limiting factor was the tire size and how much power you could hit the tires with on the launch.
The engine, tire and clutch technology is way ahead today from what it was back in the late 1970's when I ran the class.
Given the same set of rules as back then this would be a very expensive class to run
To make an entry level class you would have to limit the mods to the engine. Maybe a spec head with small valves. Flat top pistons. No port work. Small carb like a 600 or 650 Holley. Maybe allow a small shot of nitrous to appeal to the younger crowd. Limit tje max cu in to 330 Stick or auto. Stock front suspension up front and ladder bars only on the rear.

Re: Bring back super/mod...
 

I have no problem with that Mike, other then the nitrous, I would think that could get out of hand. I was thinking a 750 carb, because it's been the norm so long in these classes. I have no problem with ladder bars only, and flat top pistons, but I see no $ savings with flat tops. Explain.

Re: Bring back super/mod...
 

I've never done this exact scenario, but, say, stock cam diameter, stock lifter diameter, .700 lift at the valve roller. No vac pumps, or external oil pumps. Cast intake only. No external mods to intake, brodix spec only, polish combustion chamber, and milling only. Intake, and exhaust ports remain factory specs. They have the word spec cast into both exhaust and intake, and flow virtually the same all 3 manufactorers. Ford has a little better no. on the exhaust, but not enough to get too excited about. Just my ideas guys, not cut in stone. I know it works for the roundy-rounders.

Re: Bring back super/mod...
 

I ran a '69 Camaro in C/SM the first year they had the class. Read and re-read Rick Voglin's Car Craft articles about building his car. First year there was just the one class, which became B/SMif I remember correctly. Never had a problem running under the index. had heads from RHS to begin with then a set from MI (forget the shop's name) then a killer set from Lee Shephard. The other two sets ran the same, but Lee's heads flowed more and were faster. Had a 292", 305", and 317". Never could get the car light enough for the 292", but it was still the fastest.

I seldon had a problem hooking on 10.5" Firestones, but they started to go away after about 15 passes. Usually left, depending on the track, between 8000 & 9500.

It was a fun class. Danny Bird had a fast one.

Those rules were fine, imho. I never knew of anybody "cheating" the heads. Like building an SS car with lumps on the pistons. Some guys were trying to run them like a Modified car, trying to spin them too high. Made that mistake myself for a while. I think the heads would be tougher to police now.

Re: Bring back super/mod...
 

I agree Ed, but if a sanctioned body would put the head policing in the manufacturers hand, it would save time and money. There is a way, but I don't pretend to have all the answers. The heads are so close to equal, I don't know why we couldn'tt at least give them a look. I think I owned Danny Byrd's camaro, a 67 I purchased from Linden Bodnard from Canada in 86 I believe. I ran it in SS|CS and later in C\EM.

Re: Bring back super/mod...
 

One class is all thats needed. One sealed Circle track 400 hp Chevy motor. Only one trans. Pg or stick. ANY Stk or SS or Comp door car chassis at same lb per cubic inch. One carb 750. WOuld S/g car qualify for that chassis?with ballast? Build it yourself motor could be another variation class but cost would be problem.

Re: Bring back super/mod...
 

X2!!!

You want to make it a bit affordable and with a limited budget?
Just like others suggested...and few more limitations...

1970 or Newer cars
No FWD Conversion Cars
360 CID max
Cast Iron heads - Inline Only, No canted valves.
Flat Top Pistons
Steel Rods
Cast Aluminum Intake, no sheet metal intakes.
750 CFM carb
10.5" Tire Max
No Crank Trigger Ignition
Wet Sump Oil Pump Only
No External Vacuum Pump
No External Timing Belt Drive
All Steel Body, Fiberglass limited to Hood
No Clutchless trans, limited to a single disk
Powerglides Only.

This will test the engine builder's ability to make power and also the driving skills

Re: Bring back super/mod...
 

Please, let older cars in. I would have no problem with the rest of your rules, but too many 60's cars ready to go.

Dick, it always appears that in your world the only product or make to race is a Chevy!!!
