760Diehard, The sunstrand is the brand of the hydro, previous to mid 84 it was an eaton, which was known to give trouble. it was a good hydro, but not big enough. the sunstrand is the only way to go. for reference, the 6 cylinder is about 150 horse power, where a v8 would be about 180hp or 209 with the power kit. i do not think a 760 v8 had as much power as the 860 v8, but i am sure your machine has more than the machine for sale. feel free to email me, depending on what you are doing with the machine it might be great...or it might be terrible...bradh_44@hotmail.com brad
