Well after many delays and finding hard to get parts, i have
installed the 5.0 engine into my 94 S/C . The engine has fresh rebuilt GT 40 iron heads, a ford racing e-303 camshaft installed, advanced 2 degrees, with a
ford racing multi index timing chain. I have the GT 40 a-50 lower intake installed right now with a 95 cobra upper and 65mm t/b to be bolted on after all the
wiring, ect. is hooked up. I also have a set of jba shorty headers to put on after i install the 2000 4r70w transmission. Ahh the transmission, thats where
alot of research has gone into this project. At first i was debating a 5- speed swap or use the auto. The car came with a 94 4r70w trans and i was going to
just use that hoping it would be okay as the car had only 138 k on it. Well after doing some research and finally finding someone who could and would answer my
questions i realized the early 4r70w tranny would not cut it. The transmission has gone through numerous updates and the 99 up models are by far the strongest.
so i found one at a wreckers from a 2000 3.8 mustang and took it apart replacing, bushings, seals and clutch packs. I did this with the help of Dan Gilsdorf on
www.clickclickracing.com aka silverfox. He is a great guy and is very helpful. To control the trans, i am using
a U4PO pcm from a 94/95 5.0 sn-95 mustang. A few guys on the tccoa use this pcm and it has the same pinout as the 5.0 bird. In order to make it work i have a
custom tune from lasota racing for the shift points,ect. I also had to change over all the solenoids to the early style as they have a different ohm rating
designed to work with the early pcm. I also did the j-mod and have a 3000 rpm stall lockup torque converter for it. It turns out i didn't have to replace
the clutchs in the trans as they were in really good shape but i decided to do it anyways. I am very glad i did all this and now have a bullet proof tranny
that will easily handle 500 hp and after dropping the pan on the old trans, it was shot, the old style parts that are prone to go were shot, the 1,2
accumulater was twisted sideways in its bore and the pan was filled with metal. If any of you guys have an older 4r that is on its last legs, i would highly
reccomend this swap, all you need to do is replace the solenoids to the old style. Anyways, the one thing i was a little worried about with this swap, was
would my engine mounts work? I had read before of others trying to install a 5.0 into a v-6 car and could not make it work without the crossmember. I ran into
a guy on the tccoa and he makes custom mounts that would allow this to work with no problems he claimed. I bought these off of him last fall as he only makes
up so many at a time when he gets enough orders for them and he had one set left so i took them. They are really nice, tough mounts and although they were hard
to get installed (tight fitting), they did the job so at least that worry is out of the way. I was going to install the tranny and engine together as a unit
but after all the wrangling i had to do to get the engine bolted up while test fitting it, i decided to leave it installled and will install the trans from
underneath. Once the trans is in, the fun part begins, bolting up all the accessories and wiring, at least there is a 5.0 car at the pick and pull this
spring.
