your gonna need aftermarket cams to hit your 400rwhp number...but good luck..it will be interesting to see how close you get..im guessing around 380..but that's just my opinion.
I think 370ish is what Livernois was getting with headers/exhaust, intake, tuning..they picked up another 33 or so with the cams
