I have a 95 750 with a blown motor. Do you know if this would fit without any major changes? eg.carb, manifold etc. Also how much more power would this have? and where are you located?

this wil go right into your 750, with little changes. the exhaust manifold is different, you will need one from a 780, ( i have them here). your pipe will go right on the 780 exh manifold.
your stator, starter, flywheel front mag housing, etc is all the same, and will transfer right over.
your intake, reeds, and carbs will transfer, but you will need to rejet your carbs to 780 specs.
i would recomend upgrading to a triple outlet fuel pump for sure. you should do that with any motor you put back in anyway.
i am in southern WI, and ship fed ex daily. we take VISA and mastercard as payment options, if that helps.
going by memory, i believe the 780 is 15 to 20hp gain over the 750.
i "think" i will have a good 750 short block for sale here, sometime soon also, if you wanted to go that way.
send me an email, or call my shop if i can help in any way. thanks
