I usually trust Desktop Dyno when I contemplate an engine build. My last engine dyno'd at 484. Desktop Dyno predicted 490. Pretty close.

This time with my FE build, I'm trying some different options....Y'all check this out and see if it makes sense to you guys.

4.130" Bore
3.78" Stroke
406"

Cast iron heads, 2.09" intake valve, 1.65" exhaust valve.

10.5:1 CR

750cfm carb on a Edelbrock Performer RPM dual plane manifold.

Comp Cams mechanical roller cam. 243/.645 with a 110 LSA. Retarded 4 degrees.

I'm getting 513hp at 6000 revs...494 lb-ft at 4500 revs.

Does this sound about right to you guys?

If so, is it wise to use a roller cam on an FE block?
