Re: Cam help from Engine builders
As I recall, the old skool Comp 268H High Energy cam had a nice little lope, but not enough duration or overlap to hurt driveability. Its specs are 268/268, 218/218, 110LSA, .454"/.454". And it's happy with 9.0:1 compression.
I think that even the 270H Magnum series cam would have better manners. It has much less exhaust duration than your current cam, and a 110 LSA, so its overlap would be significantly less. But it would definitely lope.
You might want to ask for advice over on the HotRodders.com forum, where there's a lot of engine expertise.
The phone support guys at big companies like Comp have so many incoming calls that they can't spend much time with you. And I'm not even convinced they know more than many of their customers.
