4.6l and tranny swap into my '88 T-bird December 09, 2017, 11:07:18 AM Looking at my options here... i have a messed up AOD and kinda want my 4.6 and 4r75e that ive dropped so much cash into to marry and make me a nice little demon child to drive... Would it be possible to do the swap? if so, any suggestions on where to start? If its not something that is feasible, do yall have suggestions on tranny problem fix, and for more power? Im new to the platform and have only run the newer stuff... till now. Quote Selected

4.6l and tranny swap into my '88 T-bird Reply #2 – December 09, 2017, 02:28:35 PM Only 4.6 swap I remember was over on NATO. If I remember details correctly, guy had a dying Turbo Coupe so bought a 5-speed, '00-something Stang as it's replacement that needed rear tires... He totaled it on the way to buy tires, so swapped the engine/trans and all the electronics into Bird... There were several pictures, no idea if they are still online but since you have the engine would be worth checking out...Myself, I'd never swap a 4.6 into anything, but not all of us feel that way...

4.6l and tranny swap into my '88 T-bird Reply #3 – December 09, 2017, 05:57:48 PM It will fit, its not much different then a 4.6 swap on a fox stang. I wouldn't mind seeing it done. If you already have the block and parts, I say go for it.First thing though, mustsng motor mounts don't work with the stock k-member. I would probably swap to a tubular unit for more clearance, adjustability and to use stang mounts.Wiring will have to be taken from either a donor car or wired up using a stand alone aftermarket job.Everything else should pretty much go right in.

4.6l and tranny swap into my '88 T-bird Reply #5 – December 11, 2017, 12:01:37 PM I would suggest that you get a Fox Mustang k-member for a 4.6 motor as that will greatly help with the swap. Mechanically this is an easy swap but electronically this is not for those that cannot use a DVM or wiring diagrams. If this is your daily driver then you may want to back up and punt. It sounds like your 4.6 is making good power if you have dropped some change into it so if it was me I would go for it but I enjoy a challenge. Quote Selected

Also, i have been dropping in parts from LMR so ive already taken care of the K-member! Quote Selected

Also, the 4.6 and trans will be coming out of my '08 p71, the rear axle busted and figured i could just use that beast for the donor. I have the wiring and everything. Also, both the engine and trans have been rebuilt with better internals and last i checked it was pushing 301hp at the wheels( i plan on getting those numbers up) :hick: Quote Selected

If its already a 302/aod car, then its a bolt in swap with very few changes to drop in or covert to a h.o. motor.Check out coolcats.net and do some reading. Quote Selected

Modded rad support to fit 4.6 coolers. I modded the trans cross member mounts but I believe you can purchase a custom cross member. Custom drive shaft. Computer sent in to eliminate PATS and set up for a return type fuel system. Lots of things to consider, hood clearance, exhaust clearance, custom ac lines etc. Quote Selected
