For my HEI swap, I was in need of a distributor gear for an AMC 360/304, but I struck out at the junkyard over the weekend (the only place local I knew of that had one), I was a day late, they were crushing out of the truck section, so no distributor gear for me (I should've gone on Saturday). Being I am the impatient goof that I am, I decided to try to make the 258 gear work for me on the HEI, even though everywhere I've seen says, it's a no go. Onto planning, The hole for the roll pin needed to be relocated, ok no prob, drill new holes. The shaft need a bushing to fit upto the gears larger hole, now that's a bit of a challenge. The bushing needed is almost paper thin,beeing that the HEI shaft is an odd size, finding something that would just "Work" is pretty much out of the question. My solution as always, "Can't find a part, Make one." I dug around my stash of junk and found a bushing that could be modified to fit my needs, then proceded to drill my hole in the center to fit the HEI shaft.
As you can see, my hole was not straight (no dril press), now comes the fun part, how in the hell was I going to grind the bushing down to proper size, and get it back to round in the same sweep. A lathe would do the trick nicely, dad happens to have one, but not at the house, though propbably not easily accessible (IE: buried), and lets not forget, I have no clue how to use one. Enter my creation to create a part (don't laugh just yet, I assure you I was 100% sober when I came up with this idea :lol: ).
Hold back!
The video of this contraption actually working.

Sounds crazy but this haggard Red Green inspired apparatus made the bushing I needed, as well as truing my cockeyed drill error, hahahahaha.
I proceded to install the gear, roll pin, then inastalled the HEI unit in the eagle. I hit the key, instant ignition, then die, lol (no fuel line hooked up just what ever was left in the carb). After hooking up everything, fired it up, it took off like a spooked deer. Shut it back down, back the idle screw down, fired again, same deal engine raced up the r's. Arrrrgggg, I dicked with it for about 20 minutes trying to figure out what I had done that may have been amiss. I then thought, grab a flashlight and peek down the throat, sure enough, gasket meterial was hold the butterflys open. Pulled of the carb, and I couldn't believe the shenanigans I saw......
I had to walk away for a bit, ate dinner then returned to fix this mess, rtv silicon on a carburetor base gasket, seriously?
Anyway, before taking anymore backtracks I decided to throw on my junkyard carb that I had found a year or so ago, just because I knew that one was off a good running engine (at the time of removal anyway, lol).
Got it all back together, and the booger runs, kinda shitty, but at least it runs, lol (I have more things to "undo" to make it right). Anyway, here some video proof that my latest mutant does actually function, hahaha. So the verict, even though it's commonly said you have to use the V8 gear, the more readily available 258 gear will work just fine with a little minor tweaking (yet another electronic myth debunked).
