Head porting will be the key to getting you to the numbers that you want.

If you can obtain that rwhp you have the capability mid 11's - Your set-up low 12's. With that kind of HP I hope you have something bigger than a 7.5 rear.

My 2007 6.1 Hemi heads flow 360cfm ported. Similar camshaft, larger throttle body, cnc ported intake, CAI, 1-7/8” long tubes, dyno tuned, and makes 461rwhp. And I cannot imagine needing a 4000 stall.
