5.9 Magnum into a 73Duster

I agree with others on a high output fuel pump outside tank. On the 5.9 R/T truck crowd we put in the Walbro 255 gph in tank pumps in. They work great. Also when you do mod it, find a M1 2 barrel, with a 53 mm throttle body, and some 1.7 ratio roller rockers with stock cam, with aftermarket 1.6 ratio. Will make some nice little numbers. Dan
