Paxton/Vortech just installed one of there blow thru systems on my mellow 360 mystery motor in my 69 Plymouth Valiant and it is a blast to drive! My car went 12.80 at 104mph at Mopars at the Strip 2 years ago without the Paxton so it should be in the high 11's now. The car drives great also with no weirdness, the new power bonnet is way better then the old box and even better then a hat!
