I've got a 1984 LTD wagon. It's originally a 3.8L/AOD/7.5" set up. The motor popped it's gaskets at about 60K, so I tossed the 3.8L from an '84 Mustang in it. (Had to use one of the LTD headers, and should've kept the motor mounts too.) So that's what it is now, and the 3.8L is locked up now.
I wanted to go with something carb'ed, just for the simplicity. It'll cost a lot to get the 3.8L there. My brother has a 400(M) in a 1978 parts Bronco that I was thinking about using. I know I'd need a bellhousing for the AOD (400 has a big block pattern). Wasn't sure about the input shaft or torque converter. I was also curious about the linkage that runs from the TBI (or carb on the 400) to the transmission. The 351/400 is taller than the 3.8/302. Could be some issues there. The other option is to use the C6 in the Bronco, after I find a tail shaft to replace the transfer case. (Yes, I know the AOD would need to be beefed up, and I should at least get an 8.8 rear.)
I'm still learning about the 400, so any tips or info from you more knowledgeable guys would be great. Just kicking the idea around for if I don't find something easier/cheaper. The 400 is one mean sounding motor, and it won't flinch at the extra weight of the wagon.
