The Chevy 200, 229 CID and 4.3L V6 are outstanding motors. These engines are essentially a truncated Chevy V8. They make for great Jeep engines. Like the Small Block V8, the 4.3 features excellent advancements through its production span. This motor is being put into Jeeps with frequency due to its size, power, economy and weight. Modern incarnations include the Vortec V6's, which offer unusal torque for a V6 and a neat powertrain control system, in the vein of modern GM powerplants.

The Vortec V6, while short enough to fit into early "low-hood" Jeeps, is too tall for proper fit unless one is willing to do a 3/4" to 1" body lift and possibly modify the 4.3L air intake arrangement. Alternatively for these CJ2, CJ3 and M38 Jeeps, we recommend earlier versions of the Chevy V8, Chevy V6, the Buick V6 or the Ford I4.
