Who Makes Cams

Sleve the lifter bores, and use either a air cooled VW or Ford "Y" block mushroom lifter.

why would i have to sleeve the bores? could they just be bored out?

and vw or y blocks huh... dad has a 312 in a thunderbird...

one issue i could think of with a mushroom... wouldn't i have to take the pan off and install them before the cam goes in?
