340 Vs 360

If you can find one that won't cost an arm and a leg, go for it. Having a 340 would be really cool but you can really pay a premium since they're rare and valuable. In terms of performance, though, a 360 will do just about anything the 340 can. The bores are about the same 4.00" (360) vs 4.04" (340) but the added stroke of the 360 (3.58") will help a little with low-end torque.
