The '94 is OBD I and the '99 is OBD II. That may make a difference. HTH. -Jim

good point Jim, who thinks of electronics...I too am stuck in a pull choke and pull throttle mechanical frame of mind...was astounded when the MINI had no accelerator cable...just a funky black box~~ready for the future>...apparently I am not~:(

So the conclusion...aren't GT's the big honkin' engines usually like Steve McQueen in Bullit~

yeah. the 302...the "boss" 302 funny they mentioned Bullit on the wikilink there~

What if I pull the whole 5.0 including the transmission and swap it out with the 99 car

The 94 has frame damage but the 99has blown ttransmission


You'll probably have to transfer the computer (PCM), wiring harnesses, sensors, etc. as well. -Jim

Ok so its best just to scrap it then

Sir what about a 96 will the transmission work in 99

a may try to shop for parts for each and see if they are the same~

measure the bell housings, bolt pattern and length...output shaft length and diameter bolt flange ring gear and flywheel...the same? ta will work~

yeah both together...selector will poke out of the floor...mounts the same? you might have to look at these, but am fully confident the 5.0 and cruise-0-matic will go in prob~


A '96 would be a safer bet. Both are OBD II. HTH. - Jim


I have a 99 mustang and also have a 302 with tranny and wiring harness what do i need to finish the swap
