I have added a new addition to my collection,(junk pile to some family members of the softer and better smelling type)a 1965 sw 4x4. It appears to have factory air, any info on such would be appreciated. My main question, is there a good fuel injection system that would be a bolt on for this motor. I am going to put a Summit HEI, but plan few other mods to the engine other than FI. I understand Grumin vans had 292 fi,and I am wondering if they are the same as the earlier 292's. Thank you Bogiebuddy
