Here is my choice of an option. 2 Roach 2 barrels, second front) just dumps like the ends on a tripower. The dumper is progressivly linked to the rear as well. It runs on the (rear) 2 all day and have a lillte something when I downshift to 4th and pass. It is my version of the 4 barrel Holly 390 CFM but more old school with an emphisis on the More COOL!
Look at the link to fliker for a peak.
