Not sure on weight. The truck hasn't been on the scales in recent times but 3200# ish from what I was told.
Interior is basically non exsistent, the shell of the stock dash, Lexan and other lightening tricks, full blown race truck. So while not a feather weight, its lighter than most. It has a Carbon Fiber hood that was made by mopar and i'm told is one of very few in exsistence.
It will probably be a little more than 3200 with my R3 block compared to when it had a stock block. My dart is probably the heaviest A body in exsistence, so its still a step in the right direction.
Ted, My motor thinks its a big block because it's the size of one, just needs some W9's and it should go deep into the 9's.
