Alright guys, I've been putting together a build for the past few months and I was hoping some of y'all might be able to chime in on what kind of numbers I can expect. Here's the specs:

470 shortblock from Indy Cylinder Head (400 block/offset 440 crank)
10:1 compression
Stealth heads CNC ported with a valve job
hughes hydro/flat tappet cam: .592 int/.606 exh, 242* int dur/246* exh dur at .050, 108*lsa
Crane 1.6:1 ductile rockers
holley street dominator intake
1 7/8" primary full tube headers
2.5" dual exhaust with x-pipe

This build is going into a 1971 Charger, with a 727 auto, turbo action 2800-3000 converter, 3.91 8.75 sure-grip rear, and 275/60/15 rear tires.

Assuming I have and adequate fueling system and ignition system, what kind of horsepower/torque numbers and quarter mile times are y'all predicting?


1971 Dodge Charger SE 470/727/3.91 Suregrip
2016 Dodge Challenger Hellcat, 6-speed
1980 Pontiac Trans Am, Y84, WS6
2002 Ram 2500 Cummins/6-speed/2WD/QC
