Gary Lewis Posted March 5 Share Posted March 5 I guess so Gary. Just another reason to go back all mechanical and older ignition system with this hack mess. Thanks for letting me know that '82 was a 400cid. I've been a '67 thru '71 Ford truck guy for 42 years. Anymore, I get the later years mixed up. But, I'm here to learn the Bullnose trucks. The 400 is a much-maligned engine, just like its little brother the 351M. But the 400 could really have been something to love - if they hadn't retarded the cam dramatically and stuck a 2bbl on it. I know a guy that put a straight-up timing set and a 4bbl on his 400 and claimed it doubled the power. So don't give up on the engine, it is quite capable if you just give it some love.

ArdWrknTrk Posted March 5 Share Posted March 5 Yes Jim. The truck doesn't even have an ignition control module. The wiring is hacked and someone is feeding a cylinder DS II coil & points distributor from somewhere which I'll trace down when I have time. By the way, I do have an '82 F250HD with the heavy rear axle. It was a 351M truck. The harness should still have a resistance wire built in, if you want to use the DSII coil. Otherwise, get the square EFI coil. They don't care what voltage they're fed. Link to comment Share on other sites More sharing options...
Phillip G. Posted March 5 Author Share Posted March 5 so, you have more of a mixed bag already. that can muddy the waters a bit. even still, getting a fuel pump module for an efi 1986 should be a clean option. or getting a sending unit for an 86 with the 4.9 will give you the correct readings and allow an external pump whether mechanical or electric. staying with an 85/86 year should fit the tank as earlier tanks had a smaller hole. Yes, and it's a wiring hacked mess but I do have schematics for the '84 & '86 models. I can compare the two and hopefully come up with a correct wiring solution for this '86 even if it has to be a mix of both models. I'm going to cut all zip ties and separate all the wiring so I can see what is what per the '86 schematic. Whatever this guy has the cylinder coil & distributor hacked into has burned up the coil & ignition points. When I figure out how to reduce my pictures using an Android you guys can see this engine bay mess. Link to comment Share on other sites More sharing options...

Use the 'big size' button at the bottom of the right hand column. Link to comment Share on other sites More sharing options...

Oh yes, I understand. I've put aftermarket timing sets in the older Ford engines because of retarded cams. This '82 HD doesn't have an engine. I was saying that's the engine the truck had at one time. It still has the front axle, 4 speed transmission, transfer case, and HD rear differential. I'm working on an '86, I was just letting Jim know that I do have a HD truck which is the '82. Link to comment Share on other sites More sharing options...

Should I check anything in the "Float" column on the left hand side? Link to comment Share on other sites More sharing options...

I don't usually bother with any of that. But then again, I can't be bothered to re-orient my pictures either.... Link to comment Share on other sites More sharing options...
