Matman,
Just putting this information out there and my opinion.
I have a 1970 T/A with a 433CID engine with RAIV heads. The cam is a in the attachment. Engine uses RAIV exhaust manifolds with 2.45 outlet into 2.5 inch pipes. Total 31 degrees of timing all in by 3,500 RPM.
I would use this cam in a 406 with e-Heads. That's just me. Here is what the cam sounds like in a 433. Makes you wonder what the lope would be in a 406.

Boss made the video, but that is my car I am backing out.
Now, I do have a '78 with a 406 with 6X#4 heads. It has the cam in the second attachment. Here is what it sounds like. Has Doug's headers with 2.5 inch pipes. Total timing is 32 degrees all in by 3,000 RPM

The '70 T/a Has a HR with @ 050 numbers of 230/236 in a 433. LSA is 112.
The '78 T/A has a flat-Tappet with @.50 of 230/236 in a 406. LSA is 110.
Pick your poison.
