Transmission swap.

I just got a 78 Bronco with a c6\np205. I don't like auto transmissions so I want to swap in a 4spd.


I have a 79 f-150 with a 351m, np435(i think)\np205. so my question is how hard is it going to be to the parts from the 150 to the bronco?

The body is off the bronco and it doesn't have a motor in it yet, its a 460 that I am building.
The 150 don't run very well and I am selling parts, so the body will be off when I start.

Thanks to anyone with help or advice.

If you're selling parts don't sell off anything that has to do with linkage.351M bell housing bolts to the 460.Flywheel does NOT bolt up.Trans and t-case will bolt in in place of the C6 and it's t-case.You will have to swap the pedal assembly and cut the opening for the rod in the floor.I would also change the steering column but you can just remove the old shift lever if you like.I don't know if the Bronco frame is drilled for the bell crank bracket, if not, you can use the F150 frame as a pattern.The F150 has an access panel in the trans hump.You will need to cut the Bronco floor to install this as the 4 speed is taller than the C6.Also grab the speedo cable out of the F150 as you may need it.Hope this helps.

I think there's a difference between the 78 and 79 boosters which may mean there is a difference where they mount to the pedals?

I'm not sure on the booster.I'd suggest keeping the booster from the F150 until the swap is done.That way if you need it you have it.If it is the same I'd keep it for a spare anyway but that's just me.

I am going to use as many parts from the 150 as i can,

I know that all the parts on the 150 are in good shape so what ever i can swap over i will, even parts that dont have any thing to do with the transmission.

I was told on an other site that the 460 would burn up the 11" clutch pretty fast and that i would be better to put in a 12" clutch. is that true?

Yes, go with the 12" clutch.I've heard the same thing from several guys who swapped a 460 in place of 351M/400 engines.

I started working on it lastnight and I think its going to go pretty good.

I decided to put the 351m\np435\205 as one, and runn the 351 for a while so i can be sure i goe every thing working before i swap in the 460.

it will also give me a little more time to finnish building the 460.
