Good afternoon gentlemen,
I started gathering together the pieces about a year ago, I bought an AOD out of an early ninety's F-150, and pulled a rearend out of a 97 explorer.
A little history on the car, It was originally a six cylinder, 4 lug drum non-power brake car.
I just dropped the transmission a couple days ago, but I can tell you right now its not a c-4. From my best guess, someone dropped a 70's flat tappit 351w into the stock drive train of the mustang (transmission back) because I know the old four lug rear end was stock, so were the front drums.
About a year ago I pulled an 8" rearend out of a 65 to gain the extra clearance, but to my wonderful surprise it had a slightly bent passenger side axel
SO.... Here's where I'm at with the project. I've got it blocked up, old tranny out, and AOD cleaned and prepped to be installed.
I plan on buying a new 164tooth flywheel for a 92 5.8l crown vic, but I have a couple of questions.
One being, will I need to change the block plate? Like I said the engine is old school, and theres no telling what it was bolted up to stock (from what I hear an early 70's Thunderbird)
Should I just bite the bullet and grab a new one while I'm at it. I have the stock plate (I would Imagine) that was in the car before I pulled the tranny, I also have a blockplate from an early to mid eighties 302. I can take a picture of the one I just pulled from the car if that will help.
Question No.2, when I lengthen the transmission rear mount by 2", Does it need to set lower for any reason? (clearance or whatever)
Question No.3 - I installed a new 68 radiator last year so I could get the bottom snout in the correct location for a 351w. Question is, I've been running this older transmission, so the tranny cooler reservoir in the radiator is filled with the old style fluid. Will I run into problems hooking a later model Aod up to this reservoir that still has the "old" tranny type fluid in it?
I plan on running rubber lines with brass fittings just an fyi. I want to go get my flywheel today and install it, but really need answers on the backing plate issue.
And if all you have to say "use the search feature" then don't even post, I don't need anything negative in this thread and yes, I have used the search feature extensively, I would just much rather hear it from the horses mouth from people who have successfully done this exact swap.
So please, If you have anything to add make it productive. Not "why not a nine inch? ect...." I have the parts already, I've studied the swap, and I have my mind made up. Thats pretty much all there is to it.
I don't have any questions about the rear end set up at the moment, But I'm sure I will as the project continues. So thanks in advance for all the help guys, It really is appreciated
