67blowndart

I have a 67 dart. My wife recently had some work done to it and I have some questions since I didn't do the work. The mechanics put a 408 crate engine with a Paxton supercharger on it. It has a demon carb. The belts are making some noise but are brand new and tight. Also there is some hesitation when taking off and also when at WOT. just wanted to see what everyone thought about these issues. Thanks.

Those belts will make some noise..... If you feel its more that it should be.... Run it back by there shop to have them put there ear to it....
As for the hesitation.... Sounds like it need an Adjustment.... Maybe accelerator pump?

Keep up posted...
