428CJ Stock Class Valve Lift .527 ?

[Ralph A Powell]

From what I experienced is that the 62 406 never used the 306 deg cam in production. My 62 496 was a late June production car and it had the 276 degree cam. I had a insider at Ford get me a production 306 but that was not till late July of 62. He did get me a SK version in late June!

1. You're saying the .527 lift is a recent change, like in the last 20 years?
2. What cam IS that? It must refer to an OEM grind, right?
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.
