As promised here is another post on the Mach 1. This one will focus on the fuel injection and electronic ignition system.
For this build I went with the Holley Sniper Stealth EFI, as well as their Hyperspark distributor coil and ignition module, and fuel supplied by their in tank fuel pump.
The throttle body is intended at least give the initial look of a holley double pumper carburetor to the untrained eye. The hyper spark ignition system is generally plug and play with the EFI. The in tank fuel pump is a direct replacement for the factory fuel sending unit making that part of the install a breeze.
Really the whole system installed pretty easily and I'm sure you could install one in a weekend and be running. If you want the wiring to be tidy, hide components, and truly take advantage of what the system has to offer, plan for significantly more time. You do also have to be careful with wire routing to prevent any interference from the ignition system.
Taking the stealth a step further I designed a mount and cover for the ignition module mounting it to the front rail. Huge shoutout to Austin Sacket from Metal House for knocking out the clean fabrication work on those. (I went ahead and added a Ford date code just to be sneaky.) If you need any metal fabrication work for anything, you'd be hard pressed to find a more talented fabricator. Especially in Kansas. I've seen him do some truly phenomenal work and he's a great guy.
Ignore those speaker grills for now, more on them later. Also ignore that alternator for now.
I'm not a fan of seeing the touchscreen when there is EFI. it generally just always looks out of place, and I find that if you can see it then you'll just keep looking at it. So I decided to fabricate a mount that sits in the console to mount it to. It's still easily accessible if you need to look at it for diagnostics, but you can program in kill switches for several things like a loss of oil pressure. Since you can program these things in, you don't need to look at at all the time and you can just enjoy the drive and watch the road. (I wired the factory gauges to also be functional so it still has the basics visible anyway.)
The billet aluminum distributor can be bought bare or painted black. Neither looked quite right so this one got disassembled and painted to look more like a cast aluminum to blend in a bit better.
The ignition coil is indeed a hyperspark as well, but the body has been painted satin black and the top painted yellow. This again makes it look more like an original to the untrained eye.
That's enough for now. More later!
