If I didn't know any better, I'd say you don't like that grind much or feel that too many people use/recommend it

Crappiest cam grind ever and I will never understand why people are so in love with it. Thing was designed in 70's to work with marginal LA heads, not modern high quench chamber designs of todays engines. Its like recommending McDonalds as a great restaurant....it might "qualify" as food but its not. Anybody running a 268 is leaving power unused, unless they are still running mid 70's smog heads.

My Question is will 340 H.P. manifolds work with Magnum Heads?

there is about 1/8" of port not covered using them, much like putting them on a 318.
