Somewhat tongue and cheek but can be satisfying when you finally get it running. I was intimidated by the wiring but finally when it started, I knew I wouldn't have to do that again. Well, I made my plan to build up the crate engine (300 hp at 5800 rpm). Since it was already too much hp for the 19# injectors, using the Ford Racing formula I got 21+ so I knew the estimated 350+ with add ons would have to be at least 24# ones. It calculated to about 24.3 which I found acceptable. So 24# injectors it was with a matching MAF for cold air system. The wimpy 88 liter pump will have to go as well since using the injector formula backwards, you would need at least a 125 lb/hr pump. I will most likely have to use a 155 lb/hr pump. The only real wild card in the equation is the Holley Systemax which reportedly gives outrageous power between 4700 and 6500. One article documented a dyno test from 354 to 394 hp alone with other same add ons. I don't expect that much but if it exceeds the 350 target too much, I may have to change over to 30# injectors. Ford Racings says, " the injectors don't add the hp but allow the hp to be utilized if potential is there. Without the larger capacity injectors, it won't happen! I'm keeping the stock fuel rails. They don't seem to be a problem in similar builds. There is a lot of work and learning curve to get the proper tune with this setup but that will come step by step. I will start out with a basic 10 degrees and work up to 16 to 18 degrees with an eye on pre-ignition (colder plug higher octaine fuel). Other components that are not directly EFI related but will help quicker revs are the Crane alum roller rocker arms (1.7) and the RAM clutch and alum flywheel. I suppose I may have a launching problem if the engine doen't produce the needed torque under the 4700 level but in that case I will have to adjust the situation with suspension and gearing if necessary. But once it gets to it's sweet spot, I think it will be like a rocket! WEK. :cool::cool:
