dparker what does your s10 wiegh? i ran mine last weekend didnt run what i think it will. im going to fatten up the carb and try again it was running scary lean. i pulled the plugs and they looked like they hadnt been run. i havent had a chance to put mine on the scales yet. a 496 on 92 octane ran 6.82 at 100 mph breaking up all the way. i guess it did pretty good but i think it has more still yet
