In need of an education..340 vs 360.

If the 340 can get away ring job save some dollars than its an easy decision you'll be happy with either 340 gonna make the same HP just a little further up in rpm probably 200-500 rpms. 340 just need a little more stall and gear than an equally built 360. The valve seats with unlead gas shouldn't be a problem especially with a summer play toy.
