Just a thought I've seen quite a few folks very disappointed when they find out their 383 aint legal... Unless they go to SPO or GT* and those guys are pretty serious cars..

My biggest take away from this setup is that the car really performs well under the curve. If budget is a big factor, it is worth considering.
