340 max camshaft with exhaust manifolds

IMO;
The Post 84 test, is is NOT a valid test.
To be valid, the Dcr would have to be maintained.

By changing the LSA, the Ica changes, which changes the CCP.
When the CCP changes, so does the torque.
when the torque changes, so does the Power.
And torque lost, is most noticeable, at lower rpms.

Furthermore; To be even more valid, the ratio of compression degrees to power degrees would also have to be maintained, which means that each of those cams will need to be installed at different number of advance from "straight-up". This, again, affects the Ica>CCP>Torque>hp.

Furthermore; all changes will affect the powerband, which affects the average power in each gear; which is what the typical streeter should be concerned about, cuz he only has ONE gear and change to work with, until he figures out how to solve the traction issues..

From my very modest experience with lost CCP:
> even 2 degrees of CCP is noticeable. 4* is obvious.
> CCP changes between 1.5 to 2psi per 1 degree of Ica, depending on the Scr.
> therefore 4* of change can easily be 6>8ps, possibly more.
> 8psi on a 160 psi engine is 5%, which is a lot, and it translates to the entire rpm range.
