Michael, I deal with Mid America Diesel in Davenport. It came highly reccomended as well as one of the guys at work spent 15 years working there. Very easy to deal with. Good prices and GREAT service! :D

So I put in the 354 spring and am simply amazed by the jaw dropping power, I love it. The only negative is my clutch and brand new stock lift pump beg for mercy lol. No smoke either thanks to timing bump to the head w stock fuel pin.
