I'm currently in the process of installing: cam, headers, meth, low side fuel system, and upgrading to a Whipple 2.9 on my 2017 ZL1. I also had the cylinder heads CNCed. I need to know what spark plug I should be running? Also wondering where I can find a 2.8" griptec whipple pulley and what belt length? I'm going to run the 2.8" upper and 9.17" overdrive lower. Probably another pulley for lower boost setting on 93 also.
