Bell Housings, Flywheels, & Flywheel Housings

The 4BT comes in 2 varieties, Ford and Chevy - the actual engine is the same it's the flywheel housing (not bell housing) that designates which it is. You can switch between the two, but that run you $1,600 or more from Cummins! Jeff Daniel's often has new take offs or used set- ups to switch your engine. We even take take trade-ins to help offset the cost. If you plan to use a Dodge NV4500, your best bet is a 6BT set up since it is a Dodge bolt pattern. You will also need a 6BT starter to complete this package.
Certain applictaions require a simple adapter, a chevy to AX-15 requires an new bell housing (which is the adapter); others require an adapter and a bell housing such as the Ford to AX-15 set up. This requires a small block Ford bell housing which can often be found in your local junk yard - otherwise Jeff Daniel's usually has a couple laying around.
