IMO the cam on that car is too big for a SC'd setup running stock bottom end, valve train and displacment. A slightly smaller cam will give better useable powerband and area under the curve. If you really want to use the cam you running now u better be ready to take it above 7k RPM and only then you will see the full potiential of that cam on a 346 cid engine.

Great #'s
The Cam is saving the motor because the tq output is fairly low for the HP.I was looking at some of my graphs with Combo's like your's.The closest we have is 720hp but we have an even 100hp gain over yours at 4500rpm.Tq was at 620. That motor lasted about 6k miles before the rods stretched
