3+ seconds from Hoosier Autox rubber. 3+ seconds from the driver. Definitely doable.
The Cam swap will dictate more head work and more exhaust in order to maximise the package.
Do you know where the CM guy is saving time?

I have a head ready to go thats already maxed out for flow. The CM guy is has around 150-200hp on me, and has his car gutted down to maybe 3k lbs, just a guess. He's definitely pulling hard in the straights.

What does your car weigh? If he's on r comps with 2x the horsepower and "only" 500 extra lbs (guessing he's at ~3000 lbs vs. ~2500 lbs e30) and only putting 4 seconds on you, I definitely think it's doable. I can't wait to get my e30 up so I can get "serious" about this sort of thing ^_^

I need to reweigh it. last time it hit the scales at something like 2620#, but that was before the cage and skid plate and race seats. probably still in the 2500-2600# range.

How much power do you expect from the cam? 200whp w/ the torque from a 2.8L stroker sounds awesome at your weight. He'll still have more power, obviously, but it sounds like you have a pretty big advantage sitting in the driver's seat.

Still surprised at how little time he has on you. At the higher-speed (~90 mph straights) auto-x we have here, the high-horsepower cars (corvettes/mustangs) on r-comps generally put about 4-sec on me, and that's only a ~60 sec course. That's not to say improving 4 seconds isn't a big margin, your lbs/hp is nearly twice his...

With the worked head and big cam I would hope for around 20-30hp gain. Lots of guessing here though since I don't know how much power, or weight he actually has. I'm not even sure what my actual power or weight is, lol. Never had this engine dyno'd and a lot has changed on the car since it was last weighed.

Now I have a decision to make, because I was looking at my tech sheet, and it looks like if I ditch my rear strut bar and put the stock air box back in (not sure either contribute much) I can run rcomps and stay in my current class for another season. I would only do this because I think that would put me in a solid position to break the class record at pretty much all the tracks we run at. That would be cool, lol.

What are you running for an airbox now? I doubt the rear strut bar is doing a whole hell of a lot, at least when it comes to shaving time. Not sure what gains an airbox gives you, but I have a feeling a cam would easily gain you way more than you would potentially give up with a stock airbox. And R-comps would give you even more ;)

just running a cone filter, I'm sure the stock air box flows just as well. I'm sure the rear bar is contributing very little, more for looks so no loss there. If I stay in this class I couldn't do the can, so it would be just rcomps. I'm only around 2 seconds behind the track record for my class, so race rubber should put me in a good position to beat it. The record was back in like the 90's so it would be neat to break it.

only down side is I would be stuck in this class for the whole season if I want to be in the championship points race, and the car would be maxed for points in that class so I couldn't do anything to the car for a year...I don't know if I could leave the car alone for that long, lol.

I guess that's a good point - good luck not fiddling with stuff. Then again, I do like the idea of a "one variable" at a time. That's why my car still has the crummy, smelly interior. I plan to strip it, but I want to experience each change I make to the car.

Staying in your current class would give you a whole season to get to driving at your peak with all your newfound grip.
