ZF transmissions

Can anyone tell me years that the ZF transmissions were used in Ford trucks? I would also like to know if there is a differance between bolt patterns to the bellhousing on a 302 cu. engine and a 5.0 engine. Thanks for the help.

Maybe I'm wrong on this one, but I always thought the 5.0 was identical to the 302, because they're one in the same.

Josh,
A 5.0L and a 302 Cu In engine is the same . The first measurement is the engine displacement in metric and the other is its displacement in standard measurement . Your local Ford dealer may be able to help you find out when the ZF Trans was first used . Im thinking it was 86 or 87 ?

I think the ZF came onstream for the '88 model year, and were primarily used for F-250HD, F-350, and F-SuperDuty, though it's listed as being used in F-150 and Bronco also. That light-duty overkill was probably a function of transmission availability to the assembly line on that particular day.
The one to look for is a wrecked 250HD/350 with a 300-6 or 5.8 (no 302 car engines used in real trucks) or a SuperDuty with a 5.8 (351W). These engines all share the same bellhousing bolt pattern with the 302/5.0.

Hey Guys Thanks a bunch. I've been posting this question in the older truck forum. Now that I know the ZF transmission will bolt to my 302, How hard would it be to adapt the hydraulic clutch? What size flywheel do I need? Any help would be appreciated.

Uh, Josh, I think you're going to have to do some basic research on those questions. Here's some ideas:
1. Visit your friendly Ford parts guy with whom you've already struck up an acquaintence (WHAT??!! You haven't already done so? Uh oh.)
Compare some parts numbers.
2. Do the same with a few junkyard guys and their Hollander Interchange Manual. Do it early on a Saturday, bring coffe and donuts to share.

Fact: 300-6, 302, 351 have same bellhousing bolt pattern. Upgrade smallblock trucks use 11-inch diameter clutch assembly.
Fact: The flywheel on my 300-6 was factory pre-drilled and tapped for an 11-inch clutch upgrade(I've personally done this.)
Suppositions: a., 302 truck flywheels are factory predrilled and tapped for an 11-inch clutch upgrade; b., the flywheel is the same diameter between 302 and 351 since they share the same bellhousing.
Additionally, there are a 157-tooth flywheel and a 164-tooth flywheel. My 300-6 has the 164-tooth, and it was originally ordered bottom of the line six-cylinder/5-spd. I suspect, since the 302 is an upgrade option, that it would already have the 164-tooth piece.

The the 4.9L in my '91 seems like such an ideal candidate for a Paxton or Vortech superchargers. The factories haven't done anything with this combination, and with this engine out of production I don't think they will.
I have a feeling that this is going to be another of those "six-cylinder, on your own" things, so, do any of you inline-six diehards have any hard info on blower selection, mounting, drive, EFI and ignition mods, piston/compression ratio, recamming, etc.
Thanx, Eddie
