The 318 will last longer and more reliable but you can still get amazing power out of one. In the mopar magazine there was a 71 cuda with a 318 twin turbo'd pushing almost 600hp with only 8 psi. The 360 is a great performance motor and is capable of over the 1000hp range easily. I disagree with the whole cubic inches war. For example a 5.9 vs 5.7 you build them both n/a the 360 will win because of the wedge heads but if you go forced the 5.7 is way better because of the hemi heads. Why do you think a 426 hemi will eat a 440 alive if they are both forced induction it's the heads. Hemi's are meant for forced induction and wedges are n/a or sprayed engines they can be forced and create power but hands down the hemi is better for forced. Also you can get hemi heads for 273, 318, 340, 360s now. I was gonna build a 318 into a power house but i ended up with a 360 which i'm gonna turn into a 410 stroker twin turbo'd. If you want to be different build that 318 into a monster.
