I'm sure Dan's car is using the max allowable compression, and for an HO that would come in around 9.9:1.
On rearend ratios, You are allowed any gear ratio you want to run. I'm betting he's running about a 3.73 in that car.

Dan's Gold T-37 has 3.73 gears, an 068 cam with polylocks to get "0" lash on the lifters, 9.4:1 compression, and weighs 3675 lbs with him and a 1/2 tank of gas. That is with the spare tire and jack assembly in the trunk (nothing but air in the tire). He does have the Hop-Stop bars in the rear suspension. It has the original springs all the way around, and regular duty hydraulic shocks.

We will pull cars to P&G (to check cubic inches) that seem to run too quick and also check their compression ratio with a Whisler (accurtate to within 0.1) box. If the car doesn't pass either one, or both, they can still run for the event, but they have to make the changes to be legal for the next year, because we will check them again. When the event was catching on in popularity 12 years ago or so, we had cars that were blatently cheating (14:1 compression, stroker motors, light weight tranny internals, etc.) that we DQ'd them for teh next event. The F.A.S.T. race was born shortly thereafter. The vacumn minimum check is to keep camshafts from getting out of hand. We can't physically inspect each car for obvious time reasons, but we listen to them idle in neutral and in gear for automatics. We ask that new camshafts be as close to factory original as possible (2% of duration at 0.050" and advertised lift). We used to have a certified class that did a complete teardown and inspection the day before the event and may invite participants who want to prove their cars are legal to do this again if there is suficient interest.

I remember some of this back then. I was a little skeptical of a few of those cars runnng. Glad to see you guys enforce the rules. That group that branched off started their own events and actually have quite a few of them throughout the year at various venues, calling it F.A.S.T. that I touched on earlier in this thread, along with Factory Stock class that is ran much like your Pure Stock event.
So 2 different entities so to speak doing similar things.
