Here's my engine specs: pump gas 340, 10.5:1 compression (.040 over forged O.E.M. replacement pistons), J heads, and here is a link to the cam specs http://www.summitracing.com/parts/CCA-CL20-231-4/ . Could you give me a baseline to start at for timing (on the nitrous) with that info? I have also read that switching the fuel and nitrous jets in the NOS plate kits will fix the rich condition the factory jet staggering creates. Hope I am not being a bother, just trying to gather as much real world info from you guys as I can.
