'69 351 w with a 5 speed transmission

This is how it starts. Bought a 78 mustang cobra. Someone took out the 305 and installed a '69 351 windsor with a 4 speed manual tranny in it. Blew the 4 speed. I bought a 5 speed, think an '85.thought it would bolt right up
Not a chance. Belhousing is shorter. Now with the 5 speed transmission belhousing bolted up to the block, with the clutch, pressure plate and throwout bearing installed. there is no clearance between the throwout bearing and pressure plate fingers. The release fork is pressed all the way back against the bell housing. What is wrong here. what do i need to change to make this work. Rotating assembly has been balanced. Flywheel maynot be the original one for the '69 motor.

You probably need a adapter plate for this to work to space the trans out more. then everything should work and stop the binding.JMO

the 5 speed transmission bell housing is shorter than the 4 speed. the 4 speed bell housing will bolt up to the 5 speed but when u bolt it to the block the input shaft wont go into the pilot bearing. i think i need a different flywheel or clutch or both. what flywheel and clutch do i need.

thanks for the link. It was very useful. Conclusion is the best i gather the 76 to 78 mustangs had a 4speed that was not the normal t4 it has a longer bell housing and input shaft. therefore our flywheel is alot thicker than all the thinner 302/351 flywheels that ive seen. Does anyone have any info on this type of 4 speed? The car is a 1978 king cobra that originally came with the 302 and 4 speed. again many thanks.

The Mustang II 4 speed is a German sourced 4 speed, and it is pretty weak. No, it is not the same dimensionally as a T4.

Sounds like you have it figured out with the thick flywheel being the problem.

So you are saying that someone took the flywheel off the 302 that came in the car and put it on the 351w correct ?
