Doug Roe was a Rochester products engineer, his book is published by HP and was first published in the early 70's and probably still somewhere on Amazon. His book has had several printings and covers Rochester models B,2&4 GC,HV, Monojets, Dual Jets, Q-Jets,both std and electronic,even has the F-85 old turbo carb. He has another book on economy minded carb building, with tips, even tactics and tricks used during the mobilegas economy runs. In various hot rod mags over the years i have seen Doug's efforts reflected in two corvair turbocharged roadracers(one fiberglas bodied),a turbocharged & Q-Jet carbed Vega and Chevette road racers. At one time I think he sold Rochester parts too. There aint too much out there on Rochester stuff.
