Probably low-balling but close. I am running almost an identical setup in my 3200# 65 Barracuda. Only differences are CompCams XE268, windage tray and MP electronic ignition. I run sub 5 second 0-60 times with traction problems, and high 12's/low 13's on street tires depending on how "off" I am. Your combo should be a fairly healthy street package.
Unless 11's are what you're after............... :headbang:
p.s. - Incidentally, my 360 seems to be much happier with the DP 850 I have on it now than the 750 vac secondary unit I had on it earlier.
