Capri- I ahve been looking into doing a 408 or 416 in the future, and you have your facts right.
The small base circle cams really aren't good over 6000rpm from what I have been told, so I am getting the Crane Reo-fit lifters and run a Standard size roller cam. They switch deck heights in the early 70's 74 I believe has a 9.5 instead of 9.2, make sure your pistons and rods are for the right block. The 69 and 70 blocks are the strongest and were cast with the same nickel content.
If you are looking into a stroker give Brian Adams a call or e-mail, he gave me great pricing on a SCAT 408 kit, and he will answer any questions you have, nice guy.
