Port injected low deck project.
I want to build a ram jet style port injection system for a 400 B motor. It is going in a stick shift 70 Dart Swinger. The trans is a 1970 heavy duty A833 with the bigger 308 bearings and the rear is a 3.73 Dana 60 with power lock. The motor is .020 over with zero decked kb pistons, forged 383 crank and closed chamber stock heads. If it were a raised deck I would have simply bought the edelbrock manifold but they don't make it for low deck motors last time I checked. I just found a low deck Weiand tunnel ram base on Craigslist and I already had the offenhauser single quad top that has been cut open. They are not a perfect match but I can deal. Plan is to weld a flange around the opening and have a removable top and a front facing throttle body. Going to remove the nitrous nozzles and add injector bungs. For you guys running fuel injection, what system is suitable for this combo? I have seen a lot of people are running the holley system. What injectors are most people running? Any ideas on optimum plenum volume? I plan on using the aeromotive in tank pump set up. This is my first attempt at converting an old motor to fuel injection so any useful feedback will be appreciated
