Universal Texas Latemodel(weekly

[fishracer]

After reading Jason's excellent post, I thought maybe we should continue the dialogue. His idea of a class that all tracks could use and have a constant flow of cars. Here it goes:

 

1.) 3100lbs-55% left side weight (any rear, don't know why TSRS has this crazy rule) Crankshaft height off ground 12"- 4"frame and body height.

 

2.) Any chassis, stock clip-tube , all tube slm, all tube nascar, big springs, leaf springs, coil overs whatever. conventional steering, rack steering ok.any (When you get the weight up to 3100 the unsprung weight is less important than when you get down below 3000lb and the advantage of a rack over conventional at this weight is almost nill if you allow the conventional guys to get creative with their steering adjustments, it will still not make them any faster than a guy who uses enginuity with his stock stuff, just looks trick) Also, from a safety standpoint it would probably be better to say perimeter car, but trying to teach everyone that at 3100lb its kind of crazy to make a car leftside is just a waste of time and the object is to get car count and get as many cars as you can.

 

3.) Any body material except carbon fiber(would be better with steel or aluminum, then you would not have to check for the high dollar parts) Body must conform to the basic measurements in five star catalog or can be stock production style, no slab sided or wedge style.

 

4.) 10" wheel ok, wide 5 or 5x5 ok, any brakes (not really any advantage especially since weekly races are less than 50 laps in most cases) Any offset wheel. (One less thing the tech guy has to check and with the weight rule 55% who cares)

 

5.) Any stock case 3 or 4spd transmission with all the gears working(easy to tech) This means any muncie,T-10,saginaw etc. (This also means the T1-0s can say Doug Nash or Richmond on the case since Borg Warner sold their transmission division to 1st Nash now the Nash to Richmond.) Mini clutch ok Limited to 7.5" and with weight rule on assembly. (Hell the TSRS guys are spending that much or more on those 10,000 rpm, Quarter master big clutches and with limited horsepower they will last forver.) Steel Drive shaft only.

 

6.) Quick change or Ford 9" ok, limited slip, spool or detroit locker ok. Absolutely no triple tracks or other exotic differntials.

 

7.)Now for the part everone has been waiting for, the most expensive and contoversial part THE ENGINE.

 

To try and cover all the bases. They will be a blend of TSRS,THR,SAS and HMP.

 

350-360 cid max. Stroke must be stock for make of engine.

crank weight minimum 48lb.

rods must be steel, not titanium,alum etc.

wet sump only, no dry sumps kick out pans ok.

ignition must be stock type, msd ok, no crank trigger. 1 msd box

flat top pistons only.

heads.

gm, ford, dodge, 2.02 in 1.625 ex.

gm heads, gm factory straight plugs 58cc minimum, vortec 55cc with

1.94in1.5 ex. bowtie 62cc (nascar spec), world products/eagle 186cc ok but with 62cc.

 

ford N351 (62cc nascar spec), cleveland or windsor(no criss cross of block styles ie. stroking up windsor to cid.

dodge W40 ok (62cc)

 

 

carb 500cfm holley 2bl part 4412 or new holley hp500. tool check legal.

 

HMP crate motors-100lb weight brake

 

This will also bring up some grumbling. But hear it goes.

 

Intake-Edelbrock performer part 2101(vortec 2116) and the Ford or Dodge equivalent. The reason for this is probably for ease of teching and piece of mind for the racers knowing that everyone has the same advantage on the intake side. The reason for the intakes also is to try and keep the hood flat so no blind spots. Also for those who are grumbling about the cost of the intakes you spend that much on 1 tire and you can get them or order them at most AutoZones, pep boys or Advance or your local speed shops.

 

Spacer limited to 1"any material, straight holes only. Open element air cleaners limited to 15" dia. Again that way everyone can see what everyone else has intake wise and it is kind of a horse power limiter. The air box guys already have them inside their air boxs so they are not having to buy one. Aluminum or steel top and bottom only. No velocity stacks or venturi style air cleaners lids or bases. No KNN style tops.

 

These rules should be easily enforcable and as long as the tech people know why these were written they should be easy to explain and follow.

 

These should be broad enough in scope that you will pull in all different kind of cars and should not give any one person a dollar advantage over a guy who has a lot of skill but no bucks. May have missed somethings but tried cover the most cars available. The rules need to be even more detailed to try to cover as many holes but I already took up too much space.

 

Again the common gripe and the gripe that has killed a 1000 classes is "BUT I ALREADY HAVE THESE PARTS". Get over it and race for the future.
