Build suggestions for 340?

Hot Rod 20 ! I have a cam in my 410 with similar specs. It is a Howards cam designed by Mike at B3 engines. It is 237/243 @ 50 with 610 lift with 1.6 ratio rockers on a 112 lobe sep. My old combo had a Hughes 234/238 110 lobe sep cam and made 392 rwhp. The new combo makes 425 rwhp and now revs cleanly to 6500. It has lost a little bit of torque according to the dyno results but feels much better on the road. Idles nice at 750rpm and does not buck and jump. I do now have a victor 340 manifold now instead of the rpm air gap and trick flow heads. It hardly feels cammy now and drives much better than before. The 112 lobe sep really calms it down I think.
