I've searched high and Low! I can't seem to find anything on anyone swapping a newer 5.3 vortec out of a 2000+ Tahoe/Suburban, into a Blazer with a 4.3. Has any one seen or heard of it being done? I'd love to throw bigger and more reliable power into my 95 4x4. These engines seem to be a dime a dozen where I'm at so I would love some input! Thanks guys!
