I plan on going over 45 when I get the 454 and overdrive in, brakes and steering updated and the rear end re-geared.
As for extra weight... Have you seen my truck? It needs to go on a serious diet! It weighs 5000 lbs bone dry and empty. Maybe I should invert the visor and try to get some lift out of it...
