farmboy1989 Posted October 26, 2011 Share Posted October 26, 2011 Currently looking at a 1994 CH 613 with a 7sp. 300 hp in it to pull a small grain trailer. Was wondering what the differences are in the 300 hp engine vs. say the 350hp. or higher hp engines. What would it take to make the 300 hp a 350 hp? Would it just take turning it up on the computer or? Thanks for any info you can give!
