I was indeed referring to a TA 2 car--I know nothing about actual racing classes and whatnot. What I thought was cool about the the engine setup--basically an LS3--was that they were using an LS truck (bread box) intake, and they still had MAF running. Supposedly, it was limited to 500 horses, per series rules, but the cam chop seemed to indicate other possibilities. The truck intake and 15-inch wheels (1.25 inch-thick rotors) were interesting, but I have low standards . . .
Here's looking forward to more build updates.

Greg wanted a tame LS7 ... and 700hp is the lowest power version of LS7 I offer. We have them up to 900hp, but as you can imagine, those engines come with a lot of maintenance requirements. Besides, this thing will be a beast with 700HP.
---------------------------
I just returned from my 10 day vacation in Yosemite. I'll jump on here Monday & post some updates & some dyno sheets.
This dyno sheet is Greg's engine. It is our "Track Warrior 3 LS7".
You can see a detailed list of all the internal components in our catalog HERE.
Three things should stand out ...
1. The build components are almost overkill for "only" 700hp. That's to increase longevity.
2. The ARE dry sump is simply the best dry sump & best protection for the engine in a car with high G's.
3. The power curve is relatively "linear" which makes these engines easier to drive fast.
A few other notes:
A. The "dead on" dyno at Scoggin-Dickey shows 707hp. It will make 8-11 more horsepower once we we change the oil from Driven BR break-in Oil to Driven LS oil.
B. We did NOT dyno the engine with step headers. If we did the top end power would be the same, but the power band from 2500 to 6000 would show higher & even flatter.
C. Greg's headers are the RSRT "tuned" Step Headers ... 1-3/4" to 1-7/8" to 2.0" and will have more power from 2500 to 6000 than the dyno curve shows & be even flatter.
D. This same engine with the very basic, single stage GM OEM LS7 dry sump makes about 15 less HP.
E. The happy window power curve on this particular Track-Warrior engine is 2500-7500rpm on track.
Front end, hood & doors mount this week. Powertrain next week. Still on track to track test June 28th.

I'm back from my 10-day family vacation in Yosemite. While the awesome crew at SDPC Raceshop & my EFI Guru Scott Clark were wrapping up the LS7 engine ... Randy Chastain at One-Off Customs made a LOT of progress on the car. See photos below!
