Stay away from the Holley stuff..the LS stuff is more tha adequate..
You'll just have2have the ecm flashed
You can run a inline pump for the swap...but you'll need a return line on the tank..whether you use a Inline filter/reg or use a return rail system..you'll still need the return to tank..
The LS harness is freestanding...it only needs constant 12v, switch on 12v, and some grounds..
So its independent of the truck side..
Have no idea about the Camaro radiator
I would get the truck harness in good working order before you do the swap....thatll eliminate future headaches
A working speedo will require a convertor box or go to elec speedo
