My 79 Z28 is finally in the shop, and getting ready to start the LS conversion. The engine is a 6.0 out of my wrecked truck. I want to maintain the factory hood so I need to get a shorter intake. Will any LS intake off from a car work? Are the LS1 LS3 LS6 LS7 the same? Is there a specific one I should get, or a specific one to stay away from? Thanks.
