I did order their Chrysler specific catalog after the guy didn't seem to know what he was doing with Mopars. When I got it I see their prices are good. But Northernautoparts.com beat their prices by a fair ammount on the 360 I was doing.
When I was doing the 360 I checked everywhere I could think of (PAW, Summit, Jegs, Mancin's, Hensley's, Doug Herbert, and a couple others I'm forgetting right now) and most were close but Northern was the cheapest on quality parts for a 360.
Oh yeah I forgot to add that Northern auto parts has real good customer service also. Me and a buddy have had to deal with them on one occasion each and they were great. The only bad thing about Northern is they aren't into custom builds (strokers) I don't think.
