A friend had a intake manifold leak, antifreeze, that was discovered too late on his 2000 Tahoe It has developed a death knock. We have found a 5.7 vortec engine complete out of a 1996 Chevrolet Silverado. My question is will it work, of course changing intake manifold, necessary accessories, etc. The engine is a low mileage unit and the price is right. Any differences in the flywheel, knock sensors, ignition, or little things? Thanks
