Probably allowed the cammer engine to keep the field competitive as far as HP/weight, and the thinking that the solid axle in the Mustang would be a hindrance. Can the stock engine put out 400hp? Probably with a race gas tune, but remember that this series is about marketing and Ford wanted to also market the new cammer engine.
Early on in the '05 season it was clear the 3-link live axle was just fine (as evidenced by the success of the Mustangs) and every race something was done to remove the perceived advantage of the Mustangs.
From what I've seen, the Mustangs were immediately forced to run with more weight (heaviest car in the field), less gear (3.55's instead of 4.10's), and less power. This still holds true for the '07 season and the Mustangs are still the heaviest cars (3,300 lbs.) in the field and the cammer has been choked back to about 370hp. The Porsches actually have the best HP/weight ratio in the field, followed by the M3's. The Mustangs still seem to be winning a lot, though.
For the life of me, I can't understand why the GTO's aren't doing better. Is there some inherent problem with our suspension geometry??? I haven't really run head to head against a Mustang, but do feel like our cars could use huge improvements in the suspension department.
According to Chris which races in the GA cup he said that the GTO's were posting very competitive times but for some reason they have not finished that well. I think the best ive seen is 9th place for a GTO. Not bad but I was really hoping for a top 5 finish for a GTO since they have the power.
About the ls2 its probably a rule which does not allow it probably becuase it will have more power, but i think it should be allowed.
Hope they do better next year if the Spirit of Daytona team runs them again.
For anyone interested in the Spirit of Daytona GTO, here is a website showing off the car. It's kind of fun and it makes the team proud. Check it out.

Looks like it will be a 2-car effort starting in October at VIR. Should be interesting. Now there will be other American cars out there besides the 2 Cobalts. These are Riley Technologies developed race cars.
