Advise on 350 rancher mods
 

I have an 05 rancher 350 es/footshift combo (changed emergency shifter for foot shifter rod) http://forum.highlifter.com/upfiles/smiley/biglaugh.gifwith a snorkled glasspack exhaust, intake snorkle, Xtreme products front locker (to be installed tommorrow), 2 inch lift kit, epi clutch kit, 26 inch swamplites in front and 28 inch 589 in back. I want this mild beaste to really sing. The piston is the stock 78.5 mm. I was wondering if there is a place i could order a custom piston. I want like an 80mm ( so i can use same sleeve) high comp. Mabe like 11:1. I think the stock is 8:5:1 Also i was looking at oversizing valves and mabe a 2mm stroker. I want enough power to sling 27 inch gators without much strain I already have a highlifter cam that I can install. Any suggestions or comments would be most appreciated. Thanks in advance
