hey guys, i know this guy who has a complete 4.6 conversion (engine, transmission, wiring harness, ecu, etc.) now my question is, will the 4.6 fit in my 1985 mustang 3.8v6? i have heard that the 5.0 will drop right in to the 3.8 body, but i was thinking that most likely ford has changed alot since the 1985 engines. Any help would be great.
I would do it but you are going to have to change a few things. Get as much info before you turn a wrench, that is what i'm doing. 5.0 magazine has a modular fox (Fox Mustang 500 Project Car)build up that you can follow. i think that muscle mustang and fast fords did the same thing too. You can get their artilcles from online. There are some other websites that specialize in the modularfox craze. I am planning on doing my build up the same way as any other with the exception of going modular engine. the process is suspension, brakes, engine, apperance, etc. Tubular k-member- maximum, UPR, AJE makes them it basically moves the 4.6 forward 1 inch. it will also save u approx 30 lbs over the stock one. A car this age needs a suspension upgrade anyway.
