Hey guys, wanted to pass along some information for others looking at doing a v8 swap.

When I did my 351w swap I used a T19 from a 84 F150 (T18, T19, and NP435 are all very similar transmissions and bellhousing do interchange) with the hydraulic clutch bellhousing. I've seen all over the forum different results when swapping this bellhousing in. I literally took the simplest route.

Using the 85 F150 bellhousing, slave cylinder, and slave mounting bracket, I connected it to the factory master and line for my 91 2.9 5 speed. It went right together, and works without issue.

There's one quirk to this setup that I've just found. You can't pump up and bleed the system like normal. You've got to assemble the unit, fill it with fluid, and reverse bleed by pumping the slave cylinder. Keep adding fluid and slowly pumping til you quit getting bubbles in the reservoir when you pump it. Think you got them all? Move the system around in every possible motion, you'll find more air, then pump some more. Took about hour and a half with ample beer drinking time and jamming to tunes.

Hung it by the reservoir last night and threw it back together today after work. Pedal feels awesome, fully disengages, and doesn't lose disengagement when it gets hot.

Figured someone else might get some use out of this, any questions?

Im doing the same set-up on my swap: '87 F250 external slave bellhousing, slave and bracket. Care to drop some pics of your clutch set up?
