7.2 Key Engine Placement Points

• Left-right offset location is similar to factory at ~1-1/4″ to the driver’s side.
• Avoid installing the engine too low (axle clearance and other issues).
• Avoid installing the engine too high (transmission tunnel interference, etc.).
• Set your engine to 4-7 degrees of tilt rearwards, like the factory engine & powertrain.
• When mocking up your engine installation location, pay special attention to radiator and fan clearance.
• Firewall modifications are not expected.

7.3 Hood Clearance

Since Jeeps featuring the T90 transmission are both low-hood & high-hood models, you will need to choose your motor accordingly. Clearance for classic Small Block and high Vortec (truck style) intakes and accessories is not a problem for the high-hood Jeeps. Low-hood Jeeps will require low profile car intake & and accessory engines.

8. Driveshaft Modifications

Driveshaft length changes are often required for Chevy to Jeep transmission conversions. The #G9N kit typically requires lengthening the rear driveshaft and shortening the front driveshaft by about 2″. #C1 and #C3 conversions typically keep the T90 in the factory location, precluding the need for driveshaft length changes.

8.1 Prioritizing Drivetrain Components

Some installers, concerned about the expense of new or modified driveshafts, attempt to let the existing driveshafts dictate engine, transmission, and transfer case location, often to the detriment of the project. Our recommendation is to prioritize the correct position of drivetrain components over saving a few dollars which is usually regretted in the long run with compromised positioning.

8.2 Custom Driveshafts

Jeeps that require extensive travel or specialty-built driveshafts have this option available through several fabricators across the nation. These are normally specified after placement of the new transmission and measured at vehicle ride height. As the rear driveline gets shorter, it is often advantageous to use a Double Cardan or “CV style” rear shaft with the correct geometry at the axle to minimize vibrations and possible binding.

9. Axle Considerations

Use of factory axles is completely acceptable with this conversion. Axle upgrades are not necessary, but they may be chosen for reasons external to this transmission upgrade.
