Mike, i appreciate the info given. I've spent alot of time recently looking at turbo specific cams, specs, etc. I agree, the intake lift is healthy, but it should have a nice chug to it! I'm not planning on running a big single, instead most likely two 60-66mm max turbos.
I wanna keep the compressor outlet at 3" to aid in better downpipe size routing. After talking to several companies about end goal results, streetability options, etc, this cam seems to fit the bill....time will tell though! I'm anxious to see how it does!
Honestly, I am not completely convinced they are looking at this properly with respect to your goals.
If you are planning to run an unported 241/241/799/317 type casting with boost and conservative RPM levels there is no benefit to running a cam with lift that is beyond the as-cast peak flow figures, in fact what you want is a cam that spends more time at/below that peak number in the low and mid flow lift ranges (every time the valve opens and closes it sweeps through these area twice) to better fill the cylinders. The longer you hang the valve open (duration) the more air and fuel you can combust. The exhaust ports on the stock castings are a bit of a choke point, hence the need to favour them in an NA application. Add in turbos and the backpressure considerations between the valve, manifold, turbine housing and wheel, downpipe and mufflers - you may find that the narrow split isn't enough even in a 5.3L.
Buying a shelf cam for a custom build isn't the best solution - it is just an opportunity for Tick to move inventory off the shelf at your expense. I believe a custom cam from a guy like Martin Smallwood (who left Tick to strike out on his own) or Kip Fabre at Cam Motion would have netted a different result.
Without knowing exactly which head you are going to choose I would see a 222/230 .590/.585 114+3 cam to be more suited to your goals for a typical cathedral port head on a 5.3L - it would be as smooth as glass.
That being said, and for the sake of comparison, I am putting a 226/230 .605"/.609" 113+3 in my little turbo 4.8L - it is going to be pretty raunchy; and our LS1 has a 228/234 .624"/.614" 112+3 in it.
