From the Old School Induction and the Man-A-Fre shops in Lincoln, Nebraska comes this 4 deuce system for your Small Block Chevy. Built on a new unpainted Offy Pacesetter manifold. Unique integral mounted linkage and fuel block control and feed the big Rochester 2GC carbs highly modified in the Man-A-Fre tradition. Fully bench tuned it is 100% complete, no further modifications are required before installation. Use my installation and tuning recommendations for maximum intended performance. Compliment your hot rod or open roadster with this classic eye candy system. If you can’t find a Man-A-Fre, go with my Offy4x2!
