As Ken has said, look for the crank sensor (or it's hole), also the cutouts in the inlet ports to clear the ends of the injectors. The inlet port shape is another reason you can't normally fit an injection manifold to a carbed engine.

Given the require workshop machinery, you can machine the crank sensor hole in the block (but make sure it's in exactly the right place), i've done it, and the head can be welded on the inside so the cutouts can be machined.

But, not normally worth it.

Hi Bill,
I'm in the process of doing the same as you want to do but I do have an almost complete engine. I'de guess that a quick and simple way to ID an EFI is the hole in the block on the Alternater side in front of the clutch for the crank position sensor. The carb block did not have this hole I believe. I also believe that the EFI did not have a distributor but has the EDIS system which uses the 4 outlet coil block which bolts to the rear of the cylinder head.

I have found most of the parts including a wiring harness but I am wrestling with the idle control valve. I don't have one and as far as I can make out the manifold I have requires an external valve. I just can't find a part number to identify the correct valve. All the searching on the web seems to only come up with valves that bolt directly onto the manifold.
Any assistance would be welcome.

regards
Ken

Subject: [Quantum Owners] CVH Fuel Injection

Can someone please tell me how to identify an EFi CVH engine (as intended for an Escort XR3i) if the injectors and inlet manifolds are missing / absent ? I seem to remember that the original Ford EFi system used a slightly factory modified version of the engine, so if fitting aftermarket fuel injection to a previously carburated version of this marque extra parts were needed to make the whole function. I want to fit an EFi system to my CVH powered saloon so that I can run it on LPG and to this end have looked for and been offered an "as new" CVH EFi engine (without the injection system, of course, but complete in other ways). I simply want to know how to satisfy myself that it is what the guy says it is, as I'm not sure he knows one way or the other.
