The first step in installing the Howell TBI fuel injection is to make sure it has a good base to sit on. The Pig Truck’s intake manifold looked as though it had been on the AMC 360ci V-8 since the Jeep rolled out of the factory. We decided it was prudent to pull the intake and toss some new gaskets at it. This gave us time to clean any carbon out of the lifter valley and the bottom of the intake manifold. A new valley-pan gasket and intake gaskets will make sure the AMC 360ci V-8 remains happy for years to come.
