1991 Chev 2500 Engine swap ?

Hi all,, I have a 1991 truck 2500 , with a 305 ci TBI ,700r auto, ...The motor has died,,,,wanted to know if a 1995 4.3L V-6,, would bolt in to everything,,,,,,4.3L is a Vortec and has very little miles,,, and is TBI...I am hoping someone can tell me if the motor mounts will work for V8 and exhaust looks like same "Y" pipe......any help would be great,,,and thanks

a '95 vortec is not tbi. if the engine you have is really tbi you can make it work. if its a vortec the short block is all you can use.
