The engine is in place and ready for connections. Because of the VintageAir Frontrunner design, the engine could be installed with allcomponents in place. Notice the plug wires changed color. In our hasteto assemble, we forgot the Ram Jet engine comes with a set of GMPP underexhaust manifold plug wires. So we installed the GMPP wires and a GMPPcoil to fit in the original coil bracket. This required modifications ofthe wire harness.
