3. The only OEM cam I know of even close to .527 lift is the SOLID 306-306 duration cam used in
352HP 1960
390HP 1961-62
406 1962-63
427 1963-67
428PI 1966 only
That had .298 lobe lift which is .524 gross at 1.76 rocker.
Is THAT the .527 lift "OEM FoMoCo" cam?
Or some other cam? Solid or Hyd? Which do you run?

Can of worms indeed.

...just waiting for the letter that says the C8AX-6250-D camshaft, with 0.600"/0.0600" lift and 330 duration (273°/273° @ 0.050"), 107 LSA is also legal...
