1967 OHC 6 Camshaft

[ATT502]

1967 Tempest 1bbl OHC 6 CAMSHAFT Needed!! I seem to find plenty of 4 bbl cams, no 1 bbl camshafts. At this point, I'm not picky new or used would be fine. Any leads would be greatly appreciated. Thanks!!

Have you compared the characteristics of the 4bbl cam to the 1bbl cam and feel it would cause issues?

You pick up 20-25 hp using the 4bbl cam, ( which is available) and not having any valve train geometry problems.

If you read this article above, they say not to use a reground stock cam.
