Mild 5.3 LS build update 1

So the 5.3 with the specs from my previous post was put together and in the truck by my old man and the owner of the truck a week or so ago. I tuned WOT and the idle just a little bit. I found out that the owner of the truck is looking to change air intake tubing and the manifold/throttle body so some more tuning is needed but at the moment the MAF and some simple math tell me the engine makes around 350-360hp at the crank. a decent upgrade from 315hp from stock. and this is a cam only (so far) build. Im hoping to get some more out of it WOT and get the idle tuned better when he upgrades the intake manifold. Another update with the final tune and a video link to the idle and pulls will be posted. Until then, peace old style internet!
