Going to install throttle body injection to my 360 .Need to know your experiences and what the easiest and best full kits there are? some of the ones I see online are way expensive.How are some of the more reasonable priced kits working for all of you?Any issues ect? The 360 is a carberated 4 barrel 1973 going into my 1972 duster automatic.Running aprox 290 hp.
