What's a motor like that cost when all said and done?


That one was about $28K with all new parts and dyno time.

Your not going to get 1500hp with 10lbs of boost.


A 540" Hemi with 15 lbs of boost, on 100 octane, and no intercooler, will make about 1250-1300. Add a good intercooler and you come pretty close to 1500.
I use Bob at The Supercharger Store for all my Mopar Procharger stuff. They have all the bracketry and they know the pulley sizes to get very close on the first try.
