Hi Ken,

Thanks, yes I will be pulling the complete 5.0L engine and EDIS system from the Ford. I also have a '88 F-150 with the speed/density system as another option. I have 20 acres so it's no problem keeping these intact for now...easier to move around.

As I got the '95 Chevy running so well yesterday and it's in such good condition, I'm going to keep it as my farm truck. Yesterday I found a complete 1990 C1500 truck at the wreckers and have made a deal to pull the whole ECM TBI system from it, including the 1227747 ECM which is the desirable, tunable ECM. It has been converted to propane but I don't think that is a problem, I'll still find the right TB unit, there are lots around and as you said, they are not as critical as far as CFM is concerned as carbs. The 2.8L TBI is 240 CFM, the 4.3, 5 and 5.7 are 500 CFM and the fuel injectors are what really control the fuel delivery, anywhere from 28 lbs/hr to 85 lbs/hr so I could use the 500 CFM TB with the smaller injectors if need be. The nice thing about the 2.8L TB is that their bores are 1 3/8" vs 1 11/16" of the 500CFM units, which is a better match for the Merc manifold.

cheers
