ok a friend of mine has a 90 model chevy 1 ton dually with a vortec 454 in it the motor is suppose to be out of a 94 model but anyway the block has been cracked in several places and its just worn out so he was thinkin of gettin another block to put all his stuff in and so my question is this is a vortec block different from a regular 454 block will the vortec heads bolt onto a regular 454 block or is it just the heads and intake that make it a vortec or does the block have somethin to do with it to thanks for any help on this
