Aar,

PM me and we'll talk.

The question was can you make a 400 hp 340 with a stock stroke and OEM heads and manifolds. The answer is Yes.

X or j heads can be ported to flow at least 260-270 CFM with a fair amount (and a 2.055 or 2.08 and a thinner/lighter stem valve is a big help) but not a TON of port work and with very good mid lift flows which are the key to torque. A performer RPM and ported heads on a lighter bob weight shortblock will be a very stout package, even at Only 340 cubes. Bullet makes some awesome hydraulic roller lobes, the key to 340's is (more than any other Mopar IMO) is you gotta synch the cam and converter and give it some gear to work with.
