I'd wonder if a TBI 5.7 has enough torque to get that big sucker moving?

Is the current engine in the truck gas, or the diesel? If diesel, I'd wonder if the transmission has the correct bellhousing to fit a small block. Pretty sure the pattern on the big Detroit is totally different from regular GM gas engines.

Dunno a whole lot about those medium duty trucks though.

Thanks for the reply it was originally a Small block truck from the factory had a nylon oil pressure line get against the exhaust manifold early last year and in no time a connecting rod almost went through the side of the block it was a 4 bolt main 350, switched it to a 366 from another truck I had and last week pulling a hill it cracked a head and to be honest it never had the power the small block had, the truck I have the TBI 5.7 in was one I picked up for $200 about 6 months ago I mainly bought it for the transfer case the frame is rusted in two over the rear end and the only thing holding the front to the rear of the truck are the leaf springs.

Right now I am thinking of carbureting the thing just because today while getting everything together I noticed that this 5.7 must have been replaced at one time because it has a fuel pump block off plate in the side of the block.

Many of the TBI engines have the fuel pump blockoff plate, so don't let that mislead you. Take it off and check the cavity; not all were finished out to allow the pump and pushrod to work correctly.
