For all intents and purposes, what works with a N/A engine will work equally well with a turbo...
All these special blower cams, super wide LSAs, reverse split durations and such are just nonsense.
The hotcam will work but is very mild. I would choose something a little bigger. But then again I think running boost on a stock LT1 bottom end is utterly retarded in the first place.
Spend some money on pistons man. If you can do a turbo build, you can throw a set of forged pistons in it.

You do realize that there is more pressure in the exhaust on a turbo car than there is in the intake manifold, right?
831jd -
I've not heard of the LT1 hot cam - only the LT4 hot cam (0.525 lift) - so a whole extra 33 thousandths of an inch - it works for my setup; but one would think the folks that supplied your turbo might have some actual insight (vs. internet opinion) on what they've seen that works well.
I can tell you that whatever cam you use, header wrap on the exhaust keeps the heat in and helps the turbo spool quicker.
Have fun!

Dont start arguing theory with me. What I'm telling you has been PROVEN in real life.

I'm not arguing and I don't do theories. What I do KNOW is that as I decrease overlap (very easy to do on a DOHC engine with adjustable cam gears) turbocharged engines make more power and torque.
