Where in CT are you from, and how often do you go to LVD? A gold '67 X sounds right up my alley. (my car below)
My .02 - You've got alot of cam already, the TF would take more advantage of it, but as suggested what you really probably need more of is mid range torque, but with your 5100 stall speed it wouldn't get used. I think its worth a try, but you might be better off spending the money elsewhere.
There was a mag article from years ago from Steve Dulcich that tested a ton of different intakes on a 440 with really well ported stock heads and a 260 @ .050 solid roller. It was a 620ish HP combo and 666 HP with a tunnel ram. Link is below. The Eddy Victor was worth 10 HP peak and 10 ft lbs at torque peak of 4900 RPM over the M1. I hear the Trick Flow is a bit better than the Victor.
