On this build for her car looks are probably more important than getting ever last possible bit of horsepower.

As long as it sounds good and has more power than it had (it was rated at 345 hp stock) she'll be happy.
That and she just wants her car running again. laugh2

The 6.1 in my 2010 Challenger SRT did 417 rwhp with the mods it has.
If her Charger is in that ballpark she'll be really happy. drive

Kayse can't keep up at all now. lol
