I have 440 kit WB track cam 11:1 high compressions piston, I live in Ohio and I was told To run a 168 main what do you guys think?? I am running a white bros eseries slip on. Also I am looking for a full exhaust systemif you have one for sale email me at alljuice@hotmail.com thanks!

 

Powroll did my kit and they recommended a 165 main,but as of rite now Im running a 168.Based on that yours sounds pretty close.
