like chris said.. except YES!! you could.. he just listed what it would take to do.. the LT1 uses old style motor mounts.. the main problem is the electrical components not matching up.. so if you have the cash.. you could but their are better alternatives.. just stroke the 350 you most likely have to a 383, upgrade your heads to either fast-burns or vortec (vortec will require new intake manifold).. tune the ECU and you've got an easy 400hp motor
