Well if you are wanting a kit, the Trickflow set isn't to bad. It is typically set aside for 302/306's. You could expect 340-350rwhp, but of course there is so many variables that determine actual output to the tire and how aggressive you want the set-up.

If I had to put a combination together for a 347:

AFR 205's, Custom Cam, Systemax Intake, 1 3/4" headers (with cam to match), 80mm MAF, 70mm TB.

For a 331 I'd do AFR 185, or Canfield 195, Custom Cam, Systemax Intake, 1 3/4" headers (with cam to match), 80mm MAF, 70mm TB.

Is the trick flow kit (with track heat intake) not a good setup for a 331?

I have a buddy running a 331 in an sn car in the 12's on a very fresh motor and VERY conservative tune in an auto magic at that.

Car has tfs top end, and has good 11 sec potential.
