Sounds pretty good for a 5.3 I would personally go with a little bigger cam but that's me

 

Sounds like a decent combo. Depending on what your wanting the TR 224 may offer some more power up top.

 

I think it sounds pretty good to me. Witht he 243 heads I like to see a little split in the cam like the one you listed. I think the single duration cams are better suited to the 5.3 heads that have smaller intake valves. I think the 3.5" exhaust might be a bit overkill. I was debating a 3.5" exhaust for my truck with a 6.0, slightly more cam, less split, and AFR heads. I'll be making over 500 at the crank though...

 

Smaller cam because it's a daily driver and I just want to run the circle d 3200 because I tow about every week

 

I run the next up lsr cam they have like a 219/227 it was I think that be a better choice to me and still be good with that converter
