Well, I finally found the source of the knock in the Lemans today. Turns out that #3 isn't even moving the rocker. Cam lobe and likely the lifter are gone. Shit's probably pretty ugly. So to that end, what are the chances in hell that I'd be able to jam a cam in this thing without a rebuild and not spew its guts out. I'm guessing pretty goddamn low? Pontiac 350 (NOT SBC) and a stocker in it now. Also any advice what to get? I was looking at a Howards grind.
