What kind of suspension is under your car anyway (not familiar with them)?

Your combo looks pretty basic and to the point except your cam specs are a little different than what I usually see. Is that a typo?

If you can get it to the ground, your car should fly.

Yeah, you sure that was typed correctly - I haven't seen any LT1 heads that flow well enough on the exhaust side to warrant doing a reverse split like that, especially at the larger durations you are looking at?

Sounds pretty wicked. I would just be questioning the cam choice as well.

Very cool to see an lt1 is something that i would never suspect!

adjustable gas shocks in the rear, 90/10's up front with an 03 Cobra drag launch kit.

Cross frame connectors under the car to stiffen the unibody, tirangular subframes in the rear, and an upgraded IRS unit.

Sounds like it could be downright nasty! I don't like reverse splits in LT1's though. Otherwise, sounds like a killer buildup.

I dont agree with teh reverse split cam, especially since you are on nitrous. Also, with that much gear and that much nitrous, you are gonna need atleast 28 inch tires minimum. Also, considering its a two stage nitrous setup....take advantage of the extra torque you will be seeing and get a smaller converter, maybe a 3600. Basically, I think the converter is too big, the stall too high and the gears too short to run with the nitrous. It would be a great NA setup I think. But thats just my opinion, it may fly like a bat outta hell, hopefully it does
