4.6 swap

ok so I have a 92 sc thunderbird and a 95 cougar with a 4.6 I am really thinking hard about moving the 4.6 and putting it in the sc how much work will this be, I know I will have to do alot of work but what kind of work will it be to make sure the gauges will work and all of the other electronics like the a/c.

Got the only bird with Lambo Doors in Texas!
Thanks Luke!

It's a LOT of work, mainly wiring, to stick a 4.6L in a early SC. If we're just talking about a stock 4.6L SOHC, it isn't worth the trouble, IMO.

It was little bit of work but I've done it .Gauge clusters are interchangeable at lest on 95 cars,I'm running super coupe gauge cluster with 4.6 Dohc and everything works except the boost gauge but boost gauge will start working again soon.I reused my SC tank with fuel pump and fuel rails.All you have to do is swap all the wiring from one car to the other.

Doing the swap into a 89-93 SC is a bit more difficult than that, due to wiring/electronics changes made for the 94 model year.

Yup. With a 94+ car, all you have to do is change the harness that goes from the PCM to the engine bay. All the other wiring throughout the car is modular and will work. With a 93 or earlier, you'd have to change that wiring, the dash wiring, and possibly the interior wiring and engine bay wiring.

Correct. I ended up completely rewiring the entire car when I did the swap.

A DOHC may be worth the swap but a 4.6L SOHC is a waste of time. A 3.8L SC can be made to be as fast as a 4.6L SOHC motor. Possible as fast as the 4.6L DOHC but then there is the question of reliability... How good are you at wiring???
