60s /6 to 727 adapter

Slant guys...My 2nd car was a 67 fastback 225 slant six. Volaredon will probably know where this is. I bought it from a private owner next to the little bar north of The Homestead in Kankakee. There is a 2-story house there with separate apartments with an exterior staircase that goes to the 2nd floor. The car was sitting out front with a for sale sign $400.00 It was white with perfect small lug chrome reverse baby moons and raised white letter Firestones on it. I was disappointed it had a slant six, but it was nice, so I drove it home for a reduced price of $350. (this was in 1982 guys) Every stop sign I left on the way home I heard a bang under the hood. I made it home, popped the hood and pulled on the accelerator. That torquey little slant had broken the motor mount, and the valve cover was jumping up and hitting the frame on the bottom of the hood. I ran that engine as hard as I could, and it would not blow up! I held it in low full out throttle more times than I can count until it was screaming, and that engine held together. I had intended on putting a 318 I had in it, but it would not die. My best friend had wrecked a super nice 67 notch with a built 273 nitrous powered 4 gear so I sold him the car so he could fix the Formula S notch. He let me keep the baby moons and the slant. I sold the 6 and it ran so long I lost track of the car it went in. So... THERE IS MOST CERTAINLY NOTHING WRONG WITH A SLANT!!!!!!!!!!!!!! Happy Holidays
yup i know exactly where you mean, go right by there every morning on way to work....

but more along the lines of this thread... that engine that I picked up to get the adapter from.... I strapped it to my trailer, stood it upright (or at least as upright as a /6 is supposed to sit) and put the home made wood blocks where they were meant to go, strapped it to the deck of my trailer, got the battery out of my dead durango (dead, until I can get the parts for its 314k-mile 46RE tranny) set battery on trailer deck, connected the cables from starter and block, plus a jumper to the coil, splashed some gas into its Carter BBS, cleaned the points with emery cloth and contact cleaner and.... IT RUNS after having sat for I have no idea how long on a dirt floor of a barn...... I want to dig up a length of fuel line and dip it into a gas can and let it run for a few minutes instead of just as long as a splash of gas into the carb throat runs..... it has rad hoses, maybe rig up a radiator to stand up in front of it???? (forgot the screwdriver between the starter terminals to make the starter crank..... haha

But being this combo has a "rebuilders industry standard" #3257 Mopar starter (autozone sticker still on starter that came with it) I'm wondering if maybe there won't be anything needing to be ground out on this adapter? I remember others talking about some "direct drive starter" with a different tooth count on some models, maybe only those need whatever "ground out," to use this adapter on a /6 and an A500/518???? Were there different variations of the adapter?
From what I have read, it was used til '68/69 depending on who's talking. This crosses over the small/big crank pocket on a /6, and also the conversion between A/LA V8s.... did the V8s also have a small crank pocket? I've heard that no 727s did..... Ive heard early 273s did/didn't have a small crank pocket just like the /6 had.... don't know who to believe on that one.

This /6-727 has//// 3 freeze plug block so its an "early" 225.
cartridge oil filter
rebuildable fuel pump
il sending unit on side of block above oil pan rail instead of on the oil pump
has point dist., with the "oil cup" with spring loaded cap
front sump like Ive never seen on any Mopar engine
oil bath "bug catcher" air cleaner assy. attaches to carb by clamp similar to what a diesel turbo exhaust has..... (that I didnt get with this combo though I got the air cleaner)

trans... cable shift
brake drum/park brake on end of tail. including park brake cable still there
a flat flange bolted to drum, with a splined slip shaft yoke still attached by the U joint. reminds me of 70s motorhome applications.... not ball and trunnion.
a weird "loop" on top of tailshaft I have never seen before/ though I've heard the truck versions back then were hung from top? also has typical 727 flat flange for more common style of mount on bottom of tailshaft
a hole in top of bellhousing again like 70s van/motorhome trannys I have had, have had.
only the KD link sticking up thru trans case, since it is cable shift....
the only trans like this I have ever had my hands on, though I've seen more 727s over the years than I can recount.....

I may come back and post any numbers i can find off engine and trans to verify age..... if only for my curiosity.....
