1990lx coupe, balanced 302, gt40p heads, wolv 1087 cam, 1.7rr's, 65mm tb, 75mm maf, comp box on top of cobra lower, anderson ford pms, full exhaust, drag type susp. and tubular front end, 3.55's. traps 105mph before some mods, look for 110mph very soon

I run Autolite 103's (104 is stock). I also like the Motorcraft AWSF22C (AWSF32C is stock). I don't care for Champions...they're fine for lawnmowers but I don't like them in my race motor. You see very few serious racers running Champions. I've had some big name tuners warn me away from them. I've got a cross reference chart for GT-40P plugs on my website under the 'Tech Tips' section.
