Mechanical injection / EFI mashup

[fastacton]

Thanks guys!!! The link that Eds put up to the 2002-2007 slide setup looks like it could hold some promise. I don't know anything about these units, but I'm guessing the "body" of the spider ( the big black box that all the injectors go back to ) hooks up to the ECU, and must also have a main fuel supply to it? So I could hook it up to a Megasquirt or similar, as I have no ECU in my old analogue car? Or, I could fashion some kind of fuel distribution block to hook the injector hoses up to, and wire the injector lugs direct to the Megasquirt, and not have the Spider "body"?

That link says 4.3L, 5.0L, and 5.7L GM motors built between 2002 and 2007, so it that the GM LS series engines, series III? LS1, LS2 etc? Might be time for a trip to the junk yard soon....

Thanks guys, you are a massive help :)

The years are wrong for the photos on the link. That's a Vortec style injection setup which was mostly '96 to '99. There are plenty of them in the junk yards. Would you have a way of keeping them in place on your setup?

They're also extremely prone to failure/clogging/gunk.

I'd go for something like this:

However, I'd probably ditch the lower half and just machine the intake to accept the lower O-ring seal, and run the clamp screws into the intake. Then run a stainless line bent diesel-style to a distribution block.

Those are what I had in mind, just hadn't found time to find a source to suggest for them.
