AOD Swap???

I have a 74, 2dr Maverick with a 250 6cyl and a c4
the car runs great but on the highway seems like the engine is running a little too high rpm not to mention poor fuel economy.
I'm curious if I could swap in an AOD.

 

AOD swap on a 250 is much the same as doing it on a 302. The only difference is you will need a 164 tooth automatic flexplate from a 300. Everything else is the same as for a V8 AOD swap.

 

would that be the same as taking a manual trany from a 250 and putting it on a 302, except the flex ofcourse.

(NICE ROD)

 

so more or less the AOD should fit with regards to the tunnel,crossmembe, and driveshaft?

 

Tunnel should be no problem. Driveshaft will probably need to be shortened 1". Crossmemeber will need to be modified/replaced. TV cable hooked up, new shift linkage, coolant lines slightly different.
