High Lifter has a big bore kit to make a 400 into a 475. Has anybody had any experence with these kits or with High Lifter.

 

Check out the review we did in the Product Review section on High Lifters "High Performance Kit". We installed the kit on my "96" Foreman 400. Really no differance on the top end, but getting there is a whole lot funner. There is a big differance in low and mid-range power, able to pop a wheelie in 3rd gear. I use the 400 mostly for utility and the added power for plowing snow sure makes it a whole lot easier.
