Hey Guys, I have a 1978 Ford Bronco with the 351 M in it. I have an edelbrock cam, timing set, intake manifold and I am putting a holley carb on it. I was also looking into installing Ford Racing aluminum roller rockers. The ones I am looking at are found at the following web site. Are there any problems in putting these on? Do I have to get an install kit or anything or will they bolt right on? And will they really improve anything performance wise?
Any comments are welcome, and Thanks
