Well I've been battering with the idea of a lower ring/pinion. But after some careful consideration, I thought it would be best to upgrade to a AOD prior to, and the overdrive would be a good addition.
this is an ad I'm looking at:
1985 FORD F-150 Transmission AOD - 289 / 302 w/ Overdrive
few questions:
--from what I understand, the AOD had several different case lengths. However those used in cars and F-150's post 11/81 are the shorter length desired. Like the one in the add.
--Also the C-4 had several different size/tooth flex plates??? From what I gather the AOD requires a 164 tooth flexplate that is common in the 351 motors and (?? most 289/ 302 ??). So should i be safe with my flex plate?
--going along with that, if i need a different flex plate, a different tooth on the starter would be necessary, correct?
--next I understand that the block plate from my 289 should be a direct fit for the AOD ??
--bell housing SHOULD be a direct fit (per bolt pattern etc.) for my 289, right?
--I will have to fabricate a custom hangar for the AOD, or at least the location for it. anyone do this?
--lastly, the throttle valve linkage. If i remember correctly, there is a kit out there for this correct?
i guess overall from what I understand, the swap is relatively easy, but I'm looking for some input from you guys who have done this before. I guess for a $100 cost for the AOD, not that big of a deal, but how much more am I going to have to get to make this work??
really kind of excited to do this
thanks! -J
