thanks to all who answered carb question, it raised some more questions though. the bbs is off a 65 valiant w/170 going on a 73?-w/225(electronic ign) it had the holley(#1920). i've read that the bbs is the one to use-but i,m just trying to be sure b4 i spend time going thru the bbs. the bores measure same,but the throat/venturi on bbs is about 1/16 smaller than holley. this is not going to be a performer dart,rather a sunday driver ,red,droptop mostly for the wife. it will still retain stock drum brakes and the 13" rims,(brakes freshened w/new drums and cyls.and h'ware etc...it is a pushbttn auto. i want to get the most aggressive material i can get for shoes(dont care about longevity) only unable to find any info on that. i.e. like lots of metal in material. also want to go w' tandem crct m'cyl but dont know which one to go for. appreciate all/any info ,thanks dartvert
