what cam for 340 bored 0.30 over?

RPM's will be close to 3000 - 3200 with 28 inch tires with the 4.10's. The amount of stall or how good the converter is hads a factor in RPM.

If you do 4.10's and a 26 inch tire, it's going to jump up a few hundred.

340'srule, do you have the specs to the cam handy? Thanks.
