Very good from stock to wild, tune/jet accordingly. Though a DP can be tuff to launch or floor it and try to accelerate quickly on a low gear ratio (2.76 etc....) and a auto trans. You'll have to slowly get into the secondarys.
i am in the process of changing the car over to an auto and it has 3.23 gears....but soon im hopeing to throw some 4:10's in it...
i think i will just go with the holly for now, being the friend that has it, said he will also tune it for me when it gets on the car.
