So by this time, you may be thinking that I'm just another pro-360 idiot. Well you'd be right, but perhaps not for the reasons you might think.
It all boils down to getting the most bang for your small-block dollar.
For your stated goals in your opening remarks,of drive-anywhere/anytime the 360 will make more torque, and more power,on less cam, and through cast iron exhaust manifolds, while burning cheaper gas, and lasting longer, after having costed less to build, and not risking your very valuable, numbers-matching un-machined 340 shortblock.
But let's say you still want to use your 340, and that you have found a capable machine shop. At this point, you just need help in choosing a cam and compression ratio.
Okay, I can help with that.
