Hi all.....I posted this in the engine and drivetrain section but I never get anyone there to answer my questions....But I have had good luck in the past with my trusty old 67-72 friends....I have a 1996 burb with a seized Vortec 454. I do have a engine block from a 94 burb. Are the blocks the same? I was told that they are and I don't even need to move the heads because there were no "vortec" heads on the 454....is this true? If so all I need to do is move over the mounts and intake parts for the harness. Any more insite on this? Or is cut and dry? I need to know. And if longhorn man sees this thread....how's it going? And no I have yet to put the rocket 350 in the 72.
