The old girl made 577 HP with the Mach 5.8 injectors. It cleans out on the top end. First run is 411HP, second is 577, third is 575.

Running a relatively mild set of twins (HX40 over a gt42-02) gated to 54 psi at the moment

Edge EZ/Blue Chip three wire stack and a SO pump

Helix II cam with some mild head porting
 
Id say 7's would work well. they wont be much hotter EGT wise than the 5.7's you have now, and the Mach 7 equipped trucks I have driven were not smoky or tempremental at all
 
Good call Timbeaux...I've driven a couple of manual trucks w/ the 7's in...not sure what HP they were looking at but definatly a nice driving injector for the power.
 
yup go with the 7s i made 590 on em with a single 66 and i drive the truck everyday on the street not even real smoky unless you got your foot into it
