An adapter for Y-Block AOD is really the question now. I'm leaning towards an AOD from Performance Automatic for my daily driven street/strip 1957 Ford Fairlane 500 weighing approx 3,400 pounds with driver. I'm building a John Mummert equipped 318 Y-Block to yield over 400 HP and approximately 375 ft/lbs of torque: (http://www.eatonbalancing.com/blog/2012/09/29/not-a-race-engine-but-maybe-it-should-be/). Cam is 280 degrees advertised 228 @ .050" 107 .500", I expect to retain the stock 3.70 gears and use 27"dia. tires for street and 26" dia. tires for occasional strip. A Performance Automatic C4 would be about $1,400 less than AOD including Flat O adapter and it is 40lbs. lighter as well as 1/10th quicker E.T., but without Overdrive it will use up the engine and fuel excessively with 3.70's pushing an irritating 3,400 RPM on the freeway whereas an AOD will drop freeway RPM to a comfy 2,200 and reduce fuel consumption 15 to 30%

The Bendtsen's AOD adapter is $850 including starter and by moving the trans rearward 2" I can probably use the stock driveshaft without modification, but it's expensive and probably won't sound like a Y-Block starting up.

Gary Croan says he's still doing AOD to Y Block adaptation and invited me to call him to discuss what will work best.

Meanwhile, Summit's Performance Automatic StreetSmart AOD kit includes Converter, Lokar cable, dipstick tube and comes with a free driveshaft yoke for $2,952.05 including shipping.

Warren, Don't have a case or tailshaft, I only got the planets.

Guys,

Have sorted my long trans issues thanks to epay. I hope all works out.

Mark what did you decide??

If you want to make any AOD longer use the output shaft from a Lincoln or truck and the matching extention housing. Lincoln/Truck AOD is 1" longer due to tailshaft and Extension housing. Pete

slick56,

Some of those are pre 89 without the lube mod or the later valve body etc. Not all AODs are equal. Besides I tried contacting this seller a few years back he could not give me a straight answer. Hmmm

Frank,

I'm at a disadvantage living in Australia where AODs were never in a production cars. Ford Australia used the electronic ZF trans. To compensate I have spent considerable time researching the conversion and AODs. I'm not an expert, just a mug with a computer. I have very little it the way of people to ask about the AOD, they are not common here. I have seen reference to the wide ratio long AOD several times on the net. I could be wrong!!!

I saw the long AOD as an advantage in my conversion as the extra inch would put the rear of trans further over the cross member. Remembering that the manual is three inches longer than the AOD. The adaptor (1.5")and the long AOD(1") would give me a end of trans 1/2" shorter than standard. this would give me more choice for a driveshaft as I'm expecting that the tailshaft will end up about 54". I may need a two piece for clearance.

Here AODs come in containers as ballast in shipping containers from the states that are full of cars, parts etc. a full container is as expensive to ship as a half empty one. Cores are available but I have not been able to sorce a long AOD. I think with the charts that I have done with ratios etc that the close ratio aod is more suitable to my street driven car and my plans. Between the constant mention of wide ratio and unavailablity I was happy to find a good priced post 89 box.

If you confirm that the long AODs are in fact wide ratio and only want the planetary. I'm happy to purchase the end shaft and housing to convert the one I have. especially if you buy one reasonably soon. I'm about half way through my conversion.

I knew about the interchangeable parts, did not know the wide ratio gearing came in a hydraulically operated AOD.

The wide ratio planetary gear set came in the AODE/W aka 4R70W. I think the first ones were the 1993 Lincoln Mk8. I believe there was only one case size. You can put the wide ratio gear set in an AOD but the valve body will not give be able to adjust to the gear ratio change. Pete
