well i was looking at this kit for my 351c and one for my 2k 4x4 4.6 f150 have been doing some research on it seems rather sound but was wondering everyones take here on it? any one use it any one know any one who has it/uses it just a bit pricy but being that i get 15mpg it might be worth it on my truck
