1969 Barracuda Carb Suggestion Needed

That engine build is nice for a 360 backed by a 4 speed. I love a TQ, but on this particular build I'd go with the 750 dp holley for this reason: With a 4 speed and 4.10's, first and second gear will bang fast, and the air flap on the secondary's be open/shut/open/shut in bang bang bang style. In this particular build, the mechanical secondary's, in my opinion, would be ideal for this build. Besides, if your new to cars, the TQ may be a little more challenging trying to tune.
