WILCAP is an adapter manufacturer in Pismo Beach, CA (805-481-7639). They have a way to mount GM transmissions on many different Ford engines. Visit their website and have a look. I only relate this due to the fact - that I, myself - have had much better success with modern GM auto trans technology than the FOMOCO stuff. I started out thinking the Ford AOD would be the way to go but ....... it is very heavy and has a finicky reputation.

The 4L60-E in my Z-28 took an unbelievable amount of abuse (LS-1 / 310 HP) - and the pan and filter looked great when opened for a look at 100,000 miles. Because the shifting mechanism is controlled by solenoid actuation, several of the newer GM "E" transmissions can be reprogrammed to operate with 6 forward speeds. Having ridden many times in my buddies '55 scruby 2dr (he removed a gas hog Turbo 400) - I can tell you the six speed auto is a kick! Spendy change but he has driven the car back and forth to Seattle (from Tucson) several times now without any hiccups (and much better gas mileage from the 383).

Thanks, guys.  I really appreciate all the information.  I believe I'll start looking for an AOD transmission.

Guys will hate me but 2 shops here in SoCal have installed Turbo200R transmission in 56 Fords behind y-blocks using the Wilcap adapter. One shop fabricated brackets to use the stock pressure linkage to a cable for the 200. Just another thought.....good luck

My roadster came with a Scrub engine that I replaced with a 312.  I only bought the car because I got a good deal  knowning id change much of it.  I used the Wilcap adapter and left the 700-R4 auto in car just to see how it worked and was going to change later if I didn't like it.  It actually works well. I always had 4 or 5 speed sticks in my cars and this is my first auto.. I checked around to local speed shops and most leaned away from the AOD .  This winter I'm switching to the Y-block with 4-71 blower and keeping the 700R4...I'm not a GM guy but this part works for me..  by the way you have to use a Chrysler starter with it..
