701 has more low end because of port timing.
96-up Superjet engine, 62t/64x cases with the 701cc/61x cylinder will have the most upgrades.
Ok... so GP 760cylinder i called 64X -right?
i have two skis setup pretty similar. both have b-pipe, enhancer, ada head, prop...blah blah blah.
the differnece is, one has a 701 and the other a ported 760 (64x). i like the power on the 760 much better than the 701. however, ive let many of my friends ride them back to back and about 50% prefer the 701 (maybe cause the ski is prettier...idk)
Personally I like the smoother powerband of the ported 760 in the surf. It's more predictable and less likely to catch you off guard and off balance and has more than enough power to get you in and out of trouble.
The only problem I see with the 62T 760's is getting the right port job. Just being 60cc's bigger isn't enough to beat out the better port timing of a stock 701 much less a well ported 701.
