Build suggestions for 340?

If you have the money, go to a roller cam, set it up with some beehive springs, try to lighten up the rotating assembly as much as possible.

I have a 227/231 duration at 0.050, .530/.530 lift, 110 LSA hydraulic roller with edelbrock heads and 9.8:1 compression. K1 rods, beehive springs, crane gold roller rockers, its an excellent street engine and it dyno'd at 470hp/455 lb-ft and makes 400+ lb-ft from 2900-6100 rpm. Been together for 7.5 years. I changed it to EFI and it feels stronger yet.
