Hi! My name is Glenn & I知 new to the LS engine family. I知 currently building a 1967 C10 that will be powered by a L59 5.3. I知 going to be looking for advice on the build. So far I have the engine which came out of a 2004 Yukon. I want to make between 350-400 horsepower naturally aspirated & am not planning on going with a turbo. I am in the process of buying a set of 243 heads & an LS6 intake. So any advice is greatly appreciated!!
