    Default Suggestions For '89 Fox

    Hey all. Considering running a Sniper EFI system on my '89 Fox. The engine is a 349 with Edelbrock E-CNC 185 heads (about 10.2:1), cam is 230°/240° @.050", .563"/.592" on a 112° LSA. This is going through an AOD. The cost involved with running factory EFI (upper & lower, MAF, injectors, TB, Quarter Horse chip, etc.) just seems too much considering this engine is temporary and a 13:1 CR 408" with High Port cylinder heads is on the way. I was hoping I could use the factory fuel system (maybe upgraded in-tank pump). Has anyone done this? Are you regulating before the throttle body or letting the throttle body do it? As for ignition, I have a MSD Billet distributor and Digital 6 controller. I hope I can use them. I searched the internet pretty hard to find articles about this and all I run into is people saying it's going backwards. I like the idea of having a system that can be used on multiple engines, vehicles even. What are your thoughts? Thank you for your time!

    The factory return line is too small in diameter for any fuel pump larger than OEM.

    It's beneficial for allow the ECU to control the ignition timing. ECU controlled timing is preferred (because there are many ECU parameters/features that function off of the timing control), and use the MSD CD ignition box for increased spark energy.
