Was just wondering if I can use a different block from a different GM truck or do I have to use one from a different escalade. I would like to use a used block and wanted to know before I do all this work hopefully the 5.7 vortec are the same
All Vortecs will work. Your best option if the gasket deal doesn't work is a Vortec Long block from any number of sources. I have 2: L31 4: Bolt Main based Vortecs with Comp Cams Rollers going in my 26' formula in a few weeks. If you swap it's pretty easy to get 400 horse and 425 ft lbs of torque with out getting into exotic stuff with a Vortec...lot of bang for the buck.
On the heads you have (assuming they are the aluminum ones) have a machine shop check for warpage and barely resurface taking as little off as possible, but fresh rebuilt vortechs are very afforadble as a long block.
