I've scoured all the fbody boards, but the only thing I can find is 4215 with full tank of gas and 4 people in the damn thing. Also been told that GM put about 150lbs of sound deadening and insulation in these cars. Good friend of mine has one that is F'n suck yo face thru yo butt fast. But has no interior, full 10 pt cage I believe, 1 seat, sometimes 2, no radio, no heater, no ac, draglights, sbc, th350 I believe, built rear and told me it weight 3700lb + with him in it. I just find that hard to believe. It's winter bench racing, so no scales readily available. Any help?
