I'm in the process of collecting parts to build a 200 Ford six for my '65 Falcon Ranchero. I've built a couple of these engines in the distant past, but I don't remember this happening:
A fellow told me today that, I will have to use the adjustable rocker arms, from a solid-lifter engine, if I have install a cam that has any grind other than stock. He said the cam lobe base will be ground down, giving the hydraulic lifters too much "slop"...because of the longer stroke. He says they will rattle like crazy!
For the life of me, I can't remember what cam I used, when I built a 200, back in '71. All I know is, it had a mild street grind............because, at idle, it had very little lope and good low-end vacuum.
Anyway, does anyone have experience with lifters being too strung out and not able to run quiet, because of the extra length of stroke it'll have with a slightly more aggressive cam?
I really don't want the expense of aluminum adjustable rocker arms and doubt if I could find a good set of original adjustable rockers.
Any advice, information would be greatly appreciated.
