351 windsor cam questions
I just bought a 351 Windsor out of an 86 ecoline van which I'm just beginning to tear down. I've not gotten to the valve train yet but I'm almost positive its not a roller block based on the fact that its an 86. I'm looking to upgrade the cam and valve train so I have a few questions. I know that a roller cam won't work so I'm looking into a flat tappet cam. Will both a mechanical and hydraulic flat tappet cam work if this is not a roller block? Also, what are the advantages and disadvantages with a mechanical vs hydraulic cam?
