Some of the guys in the pro-stock class of the CVRA have been having good luck with the GM crates for the last 2 years....I like CVRA's 358 ideas about spec heads or a Jasper crate..the engine has been dyno'd to a specific HP(500)...I think it is a 383 though ....I'm not keen on the light weight parts rule(going to price us right out)

The phase in period is usualy around 2-4 years. If you noticed in 04 Dirt rule book still had the weight for a ported 358 engine at 2650 and non at 2450. They started the non port engines around '92. Thats when I built my 1st on and still have today. But DIRT is all new so hard to compare the past to today.

Fact is if dirt tech'd the way they should have we would not be going to crate motors. The rule book clearly states no porting, but 99% of the 2bl guys have ported heads. I e-mailed Mr Willis and told him how I feel and like I said if they stuck by the rules a motor would cost about 7000 not 13500. Same thing for fuel cells book says 22 max gallons, but all theseries guys have atleast 24.5 and I have been told some are 26 with a thin bladder. Dirt not enforcing the rules has caused this big problem. I have been told the laxed rules enforcing days are over and i hope so.

The rough draft of the new rules is out and there are not many changes to most of the rules except for engines.

Changes

358
Ported heads as seen fit dart 200, 215, and 230
Or brodix spec head no mods one year suspension if caught
DIRT approved msd box 7600 max rpm
112 race fuel only supplier TBA
Only in car adjustments are brake bias and mechanical panhard

Sportsmen
Crate engine with 650cfm 4 barrel
Or old engine rules with ported head as seen fit
Weight crate 2400, ported 2550
DIRT approved msd box 6600 max rpm
104 race fuel only supplier TBA
Only in car adjustments are brake bias and mechanical panhard

No two way radios in all classes
And they are going to be going with the exact dim for bodies

The final revision is supposedly going to come out Dec 15

The best one (changes) is not brake shutoffs allowed! I cant see why they wont allow us to use a shutoff in the event one breaks a brake line and crashes or runs into someone/something in the pits because he cant stop. I also wonder how many pieces of lead will fall off cars this year due to added weight. The crate engine rule might be good, but if the teching continues the same way it is currtenly being done it wont work out because someone will start cheating them up and then everyone will follow . The spec headers are a joke because they make one spend more money and I see the only reason for them is money in dirts pocket. I hope the spec engine has atleast 400hp 400 torque otherwise it will make them alot slower on big tracks

The spec header is to keep the cost down. Sportsman guys are spending $1200.00+ on exhaust way too much. It is an entry level class. If you want to spend more mony to go faster move up to the next class. I think you will see all of thier changes will work out for the best in the long run. So far I can see the lower buck guy being able to compete with the top guy in all lower classes. I have spoken to more racers that are in favor of these new rules to thoughs against them.

anybody heard which msd it is going to be a 6a ,6al or just a soft touch limiter, i had also heard something about 2 driveshaft hoops in the cars not to sure how the expect to get them in there with the torque arms i feel they should just make it mandatory that the shaft cover is made out of 1 piece of steel instead of bolting together i seen 2 of them break this past season at Merritville

The MSD box is to be a special box you will buy from DIRT.that is internally set for that classes rpm rule. Most Driveshaft shields are made out of one piece of steel. The hoops are to be mounted to the torque arms one up front and one in at rear bolted to each arm.

from what I heared is the msd must be bought from dirt that the rev limit can not be changed

the front hoop can be bolted to the torque arms or bolted to the frame and the rear bolted to the arms

If the rumors are true...The spec heads and crate rules are the same or very similar to the CVRA rules...Take a look at www.cvra.com ....should give you a good picture....They have been using these for the last 2 years...with the weight advantage they are very competitive...A crate motor won the track championship in the prostocks
