[QUOTE="mysticoupe, post: 12883798, member: 95905"] Im looming for some input on what plugs/ gap would be best on my car. Its a 95' gt with a lightning short block, gt-40 upper n lower, e-303 cam, edlebrock perf.rpm heads. I was told it was @11.1 comp. All stock ignition with a msd coil. I use ngkr tr-55's they were gapped at .40 and the car pulled really hard but idle was a lil rough, now I replaced them and gaped the new ones @ .45 it runs really smooth at low acceleration, but when I lay into it the pick up just isnt there..any suggestions? Would a aftermarket ignition help? I have a msd 6al box from an old foxbody I could try [/QUOTE]
