Many racers out there that like their 660's. I asked Mark about them and he didn't have much to say. Besides the center squirter and straight boosters what makes them so different or better than a 650dp?
I believe it is simply that they are well calibrated to a tunnel ram OOTB, and the 1:1 linkage works well for fuel distribution
