Do you all ever get ideas that won't go away?
Personally I say go for it but your going to have to beef up the chassis alot otherwise you'll twist the car around you. If you think about it your going from a frame almost 12" tall 1/4" thick by 2 or 3 inches wide and usually boxed to a frame that is maybe 1/8" and open on top. You will have alot of changes to do and the sheer size of the cummins and it's trans will be a killer to. Personally it'll be cool as heck and I say if you can swing it git'r done.
lol I have those ideas to. I want to build a roadster out of a reg. cab. shortbox dodge pickup. remove the roof except for the windshield connect the cab and bed together and make that whole space into kind of a party area with the tailgate welded smooth. and then theres the same idea with instead an old Cadillac hearse the ones with the kind diamond shaped taillights but with that diamond top shape carried from the windshield to the taillight. Or my late 30's plymouth with a custom grilled made out of two 57 chevy truck grilles welded together bottom to bottom on it's side but the width made shorter to match the height of the grille. lol lots of ideas to little money
