It's a super t10 4 speed manual w/ a 2.88 1st gear.makes for a great cruiser. Would the 3.08 be a big difference in rpm compared to the 2.56?

It will make a noticeable difference. It is all relative to what you are use to.

2150 rpm with 2.56 gears and 26" tall tires at 65 mph.
2587 rpm with 3.08 gears and 26" tall tires at 65mph.

Hope this gives you an idea of the difference. Jim
