Build me an Alky 440

Mike,
The hardest thing about the hilborn and the enderle injection is the adjustment of the barrel valve and the nozzels in the ports to get the correct amount of fuel to each cylinder, depending on which type of injector that is being used. What I mean is if it's a stack injector or a hat injector, stack's have to be closer tuned as you have one throttle blade per port where as the hat has all the air comming from one spot and then mixed by the intake manifold. And the adjustments aren't as fine tuned. Then with the Ron's injection he uses a nozzle something like a pro shot fogger NOS system and the nozzels are metered to flow the same where as the Hilborn and the Enderle aren't and you would need a fuel flow bench to get it right. With the Hilborn and Enderle injection systems the nozzels will vary as to the amount of flow that go's through them even if they are the same # like 37's or 40's these #'s are just for reference and not for how much they flow. Most blown and injected engines have larger # nozzels in the front and smaller ones in the rear as the fuel is harder to keep in the front because of the G forces so they are generally richer than the rear. But you will learn this as you mess with it more.
The Rons is simpler as with his you just plum the lines and use his nozzels and set the barrel valve and your done, his nozzels are flowed to a certian flow then mated with the injector for the engine used, weather it would be a small block or big block, he takes alot of the guess work out of the equation and is more suited for bracket racing and not for all out performance, I've seen some of his stuff run as fast as 4.70's in the 1/8 @ 150 + mph when tuned right. After that you would need a more serious set up like the Hilborn or the Enderle as Rons just doesn't have the air flow capabilities that the others do.
