Well, one of my buds is finally gonna get rid of the ole 258 for a 4.3liter injected mill.Heres the problem. He has the np435 ford 4 speed and t176 bellhousing. What kind of bellhousing might actually bolt up the ford tranny and the chevy motor? I'm sure advance adapters makes one, but I'd hate to have to spend more on a bellhousing than than what he spent on the engine !! Anyone have any pointers?

It's as close to a 1ton as it can get and still be a jeep!!! Gotta love it!!

The 1980 - 1982 Jeep 4 cylinder (Iron Duke) was a GM engine. The bellhousing from a Jeep Iron Duke 4 cylinder has the same bellhousing bolt pattern as the Small Block Chevy. The NP 435 and T-18 can be bolted to the 1980 - 82 Jeep 4 cylinder bellhousing. The Jeep Iron Duke 4 cylinder bellhousing will allow the use of the Camaro 10.4" clutch. The Jeep Iron Duke 4 cylinder bellhousing used a hydraulic clutch, with the slave cylinder bolting to the bellhousing.

I have two of them, looking for one? I'd sell one of them. I also have a spare hydraulic clutch setup I'd let go cheap, it needs to be rebuilt, but even includes the pedal.

I have the Jeep T18 in mine. Would the Iron Duke bellhousing work on mine to convert to a SBC?

JEEPN, how much is cheap?

Yes, the bellhousing would allow you to connect a SBC to a T-18.

For the clutch, $50. All the pieces separately are about $180, and that doesn't include the pedal. I rebuilt mine on the Scrambler, and it works well, I'd do this one but I don't feel like messing with it. It still had the line attached and fluid in it when I picked it up about a month ago, so it should be fine. It will need a new line though, the one that was on it was a little dry rotted at the center of the rubber section.

Just wanted to add some additional information about the Jeep Iron Duke bellhousing. The 10.4" Camaro clutch is smaller than the 11" clutch used in GM pickups. The holes for the T-18 / NP-435 need to be drilled and tapped into the Iron Duke bellhousing. The Iron Duke bellhousing has extra casting in the bellhousing where the holes need to be drilled and tapped. The Iron Duke bellhousing requires the smaller 153 tooth Small Block Chevy flywheel and will not allow the use of the pickup high-torque starter that the usual 168 tooth flywheel used in most pickups. For a mild 4.3 Chevy V6 the 10.4" car type clutch is OK. For a mild built 350 Chevy, the 10.4 clutch is weak/wwwthreads_images/icons/frown.gif. I also have an extra Iron Duke bellhousing I'd be gald to sell cheap, I needed an 11 clutch and high-torque starter.

With my SBC conversion for my 80 CJ5 I used bolt in motor mounts from M.O.R.E. http://www.mountainoffroad.com/catalog/BombProof MM/bombproof.htm . I'm using an AMC 304 V8 4 core radiator that had the inlet / outlet modified for a GM engine and an electric fan. I using over the fender Hooker Headers and glass packs for an exhaust system. I had to cut the inner fenders to use the over the fender Hooker Headers.
