Tunnel Ram 383

just to add,i ran a tunnelram and it ran great even overcarbed,would probably have worked alot better with less carb,but there realy is no blackmagic to it they are basic and works as long as you dont put a tunnelram with way big carbs on a lowcompression shortblock with way to much cam,thats what gave them the bad reputation they still have. and i would NOT run the carbs on progresive linkage, 1:1 is the way to go,just picture what happens to the fuel mixture when #7&#8 has to draw the mixture from the primarys on the front carb about 12" forward in the plenum. look at the tunnelram as a I.R system with a plenum added to help these to be honest crappy carbs out with lessending the pulses that Holleys and Edelbrocks realy cant handle,they are designed to work with a steady flow.
