get hold of rich @ firecore wires (a moparts member and sponser) and get his combo and info. his car is close to 4000 lbs and he was clicking off 10.85s at norwalk this year @ the mopar event. i can't give you #s on mine but desk-top dyno said 625 hp. that's a .020 over 426 with stock stroke, mp alum heads with port clean up only with a crane hyd roller with 564 lift intake 555 lift exhaust (advertised lift, i got a little more with different ratio rockers), duration is 236 int and 240 ex @ 50. small 2" hedman headers with a new mp crossram and 2 holley 770 carbs. starts easy and other then idleing a bit high (900 rpm) it runs and drives nice. i but 450 miles on it from aug to oct and had very few issues. even got 9 mpg if i kept my foot out of it. most guys tend to think on a street car a single carb will make more hp. dave
