MSefi.com read only forum (Jan.15,2018)

I'm new on this forum and I'm just getting into EFI, don't know a lot about it as yet, but I'm sure I'll learn. I have an early Hilborn mechanical injector manifold that I've had for some time, fits a small block Chevy, my intentions are to convert it to EFI. I'm just looking for anyone who has already done this or knows something about it. I know it can be done by some companies out there, at great expense, since I'm kinda limited on funds I'll have to do it myself. So, I'm just looking for suggestions, ideas, or any type of help. This is going to end up on my 1940 Ford Deluxe 2dr Sedan Hot Rod, kind of a nostalgic look in the engine compartment.

Thanks

I am doing the same with an early Hilborn on a sbc. I bought injector bosses from Kinsler and used a hand drill to make the holes for them in the manifold. I then epoxied them in. Both Hilborn and Kinsler sell fuel blocks that have fittings that have 2 sets of four connections that allow you to use one set for fuel and one set for MAP signals. There is a guy who is on ebay that sells machined efi bosses that accepts electronic injectors and screw into the old mechanical injector boss if you want to go that way. He also sells adapters that allow you to adapt the mech lines to the efi injector. Since the older stacks are usuall vertical one can design an airbox using a scanner and a muffler pipe bender. Use the scanner to create a template to make the base and use the bender to create a lip on the correct size exhaust pipe. You then epoxie them to the base and make a top. I have 8 4in chrome stacks to use for the car show gatherings.

Welcome to the site Steve
It sounds like a real good project 40 Delx nice , On your manifold do you have inboard or outboard injector fittings. How much of the old school do you want i.e. fuel lines or fuel rail, injectors inboard or out. If the injector bosses are on the outside then you can use them as you vacuum line then plum the bottom for IAC lines you will need a vacuum log to smooth out the pulsing of the cylinders. A lot of this will depend on your available tools and skill level, welding (TIG) will have a better overall look than epoxy (I'm not totally sold on epoxy yet) let me know if I can help. I have gotten my parts from Kinsler (248) 362-1145 ask for Scott) the link in my sig has pics of my manifold.
