wish I could say that ... but some 215 injectors, 181 dv's, 15-16* timing, 4k springs, and a turbo of your choice shold get you there. The hx35 will move enough air for 350 to the wheels.

i been looking at parts and ebay plates are wicked cheap, would you guys recommend those or not? thinking a #6 or #8. does the governor spring kit really help that much? i pretty much just daily drive this truck lookin for some extra power just incase.how about afc spring kits-yes or no? any websites that sell good stuff would be helpful.
thanks matt
