i can see a 13.6 happening. driver could shed another 30 lbs. too
the bosch +4 plugs are worthless. I've heard a lot of bad things about them, namely the ground electrodes shrouding the spark because there's too many of them. Hell, we just had a ricer in the shop who had switched to the Bosch +4's, and the thing was running rough as hell because it wasn't getting complete combustion. put the mfr.'s recommended plugs in, and it ran nice and smooth.
