Purchased a 5.3 from 70 deville over the weekend. Dont have a car to drop it in yet but have my eyes on a couple of different G Bodies. Hoping to be at or around 500whp N/A for under $3k, is that doabale or wishful thinking? This will be my 1st non Mopar build, so I have no clue about these LS motors. People have told me h/c/i should get me around 500 to the crank. I have also heard LS6 heads vs aftermarket heads is the way to go. Again, I am clueless on what works and doesnt work on these motors. Any and all help/suggestions is much appreciated as I'm looking to get started on this project asap!
