Re: Ram Air IV versus 455 HO
My engine parts are at my machinists right now. They are also recommending a hyd roller cam so I guess before I commit to a roller I need to know that I don't have to modify the lifter valley at all. And what Comp Cams hyd roller. This SD block has all that extra webbing around the lifter bores so I don't want any suprises.
