The car is completly gutted exept the factory glass, so it may very easily be under 3150lbs, but the 87 firebird with a sbc and stock rear (did still have bumpers in it though) that I had weighed 2850 with me in it. so I guessed this one may be about 300 lbs more with the iron bbc and the 9" ford (driver may have added 30lbs too).
Thanks for the input keep it coming.
