Looks really nice Tony and that cam did better than I thought it would. That engine would be a real handful in a street car. Probably blow the tires off of most anything.

The intake manifold vacuum is telling you that you need a bigger carb at WOT. If you were local I'd loan you my "true" 950 Holley just to see how it works. Most of those 1000 cfm carbs are actually an 850 venturi.

I'd also loan you a set of 2 inch dyno headers which would probably pick up the torque. 2.250 headers are huge for that engine.
