Here is an update: I blew up the original 4.8, spun a center main bearing. I bought a 5.3 engine, and while it was out we installed a cam. We bought the BTR stage 3 ls car cam. We had the car tune somewhat ourselves it's get to get it running and driving to the dyno shop. Here are the numbers

330 whp
320 tq
4l60e
17in 40x 235 tires
Btr stage 3 car cam
truck intake
Double valve springs with stock length pushrods

I have looked into the tune yet I might tweak at it some.

You usually see a lower torque number at lower rpm -- but just like peak HP, peak torque should go up with the more aggressive cam, albeit at a higher rpm.

Here's a swap without pulling the heads - suppose that spinning the cam and inserting those long rods is the trick/tool to hold the lifters up.... https://www.youtube.com/watch?v=Z35r-8NpLbs; or maybe the aluminum block engines are different?
