Its too much for me, kinda lunges & spins the tires alot, even just trying to ease around the yard. Power is simply unreal, he can hardly keep it on the road. He wants to take it back to the track to see how well it does,(his best befroe was 10.23/108mph 1000ft) but its closed until NewYrs here. It turned out to be an 8/71, I thhnk it is at 4%overdriven. Has the birdcatcher setup, & belt-driven fuelpump. Brian
