My 408 build

On the street my W2 head 408, 4 speed, 3.23 geared Dart will vaporize the tires at any speed in first or second gear with the Victor W2 on it. On street tires 3rd gear rubber is normal. No loss in low speed torque with the stroker, traction is the limiting factor. Cam is 237-241, .580 lift, 106 lsa.

Your automatic, mid stall convertor, and 3.91's will be into the torque fast enough anyway. It is my opinion, anything but a good single plain will hold you back.
