thanks, i did change plugs on it and it runs sssoooo much smoother!! I am installing MSD EVERYTHING next month including the ignition. Everything will include; cap, rotor, module, coil, wires, & msd 6A ignition. This doesn't mean i will beat the crap out of it. My 4.1 stock with load in the back is WAY quicker than my dads! I'll have the fastest 4.1 around, it might even be quicker than the 4.5 which is the same shit. What if i set my timing to 12 degrees and ran regular?
