The Vig 3600 stalls to over 4200+ and the 4000 will probably stall to 4600 or more NA. It might work NA, but most people have the best luck with the 3600.
As soon as you spray it, you'll stall really high. With the spray you can make good torque in the mid range. Having it slip real high on the spray kills you unless you can spin the motor pretty high. With a stock cam, that is not optimal.
