Coupla comments on your engine profile. Use Desktop Dyno myself, and used it to spec the engine I'm using now.

If you're building a 393, the stroke needs to be 3.85".

If you're using iron Windsor Sr. heads, make the CR 9.5:1. Aluminum, go with 10:1. (My actual with the TFS's came out to about 9.75:1 - no pinging on pump gas)

For a 393, a 750 CFM carb is good. For a 351, might want to use the 700 Holley, or 650 Speed Demon (which supposedly is good for about 680 CFM).

For a small block, even a big small block, run the program with small tube headers and mufflers. CR primaries for the 351W are 1 5/8" ID.

Correct me if I'm mistaken on this, but that Wolverine cam is a hydraulic flat tappet, not a roller. Try plugging in some of the current hydraulic roller grinds from Comp, Crane, and Crower and see what you get.

One of the things that grabbed me when I profiled the 351 side by side with the 393, and no other changes was the 393, at 2000 RPM was putting out 50 more fp/tq than the 351. At 5500 RPM, the 351 caught up to it. Enlarge the intake valve on the 393 to 2.08, and the 393 gets its top end back. Then add the 750 CFM carb, and the 393 starts using it.

Just for fun, bolt a set of 351 Cleveland 4v heads on the 393 (2.19/1.73) and see what happens.
