Armish;185]Edelbrock is now offering upgrade kits that allow anyone with a first generation Pro Flo kit to upgrade to the new Pro Flo2 system. The upgrade kits include a system harness.

At this point, since you know that 42's are an option, I think your choice is between the 35's or 42's. The 60 lb injectors are really for engines that are projected to make over 675 hp. If you'll be purchasing direct from Edelbrock, I'd probably go with the 42's. Speedlink73.
