What jets did you have in for that run? Dean Oliver is the guy to talk to about 4GC's, I have tried a multitude of different jet set ups and have found very little performance gain in the the 4GC. I have 67/69 jets in now and will likely end up with 68's in all. As for laying down at 1000 ft, it's a 283 all my car does on the top end is make noise!
