I'm trying to find information about the Ram Jet 502 MEFI 4 systems that uses the crank position sensor. Does anyone know which MEFI 4 (4, 4a, or 4b) uses the crank position sensor? Does anyone know if the Ram Jet 502 uses the same 4x crank trigger wheel as the 96 - 2000 L29 / Vortec 454?
Any help is greatly appreciated!
