FE and AOD?
I am building a 390 (as my sig says) and am currently running a C6 behind a 360. I would like to swap this with an AOD in my truck, (see sig) to get an overdrive gear. Is this possible, will it require an adapter, or is it bolt in? Any other concerns? There's a junkyard full of 'em by where I live...

The FE has a unique bolt pattern and there are no factory bellhousings that will let you bolt the two up. There are some aftermarket ones out there but they are rare and I can't remember where I saw them.

Don't waste your time with a scrappy special. Even the '88-93 boxes need mods, esp to hold up to a 390, esp if it's anything other than a 360 with a 390 decal on the aircleaner.
AOD to FE adaptor here, bring $850 for the AOD, $875 for a GM 700r, arguably a better trans. Scroll down about half way:
AOD Transmission from PATC, AOD Transmissions
I think you could find a usable stock 700R as GM put them behind some higher output motors. But, built AOD or 700R, in the $2000 range.

I assume you are rich as you are building a 390 with $5 gas on the horizen. But even if I was spending your money, I wouldn't spend $3000 for one of those, I spend it on a Gear Vendor unit, bolt it to the C6 & and save the adaptor/linkage/cooler/shifter/other headaches.
Gear Vendors under/overdrive transmissions the most awarded auxiliary transmissions.
Happy motoring!
BTW it's no better for a manual OD for an FE. This is getting to be a common thread for some reason.....
