1989 Jeep Comanche with a 4.7 L Inline-Six

StinkyFab Racing (SFR) built this 1989 Jeep Comanche called the “Lab Rat” to develop and test new products at their company in Escondido, California. Under the hood sits a 4.7 L inline-six built by Bishop-Buehl Racing Engines capable of 285 hp. The motor features a Scat stroker crank, Bishop-Buehl pistons and H-beam rods, custom ground Comp camshaft, ported head with LSx valves and springs, and custom 2.5-inch exhaust. The motor is paired to an Aisin-Warner AW4 four-speed automatic transmission and NP231 transfer case. Power is split between a Dana 30 front axle with a Powertrax locking differential and Dana 44 rear axle with a Powertrax Grip Pro differential and 4.88 ratio. StinkyFab Racing installed a SFR Long Arm 4-Link front suspension with RockJock4x4 Anti-Rock front sway bar and SFR Premium 7075 aluminum 1-ton steering kit. In back are custom SFR shackles and Bilstein 5165 remote reservoir shocks.
