going to be finishing up the engine install soon (i hope), and was thinking about if i should run an AFPR with a bigger cam and more lift? and what the "advantage" might be? (LT4 hotcam, going to .525 lift w/1.6 rockers) thanks...

An AFPR is always a very good tuning tool. With the right dialed in fuel pressure, you will maximize your RWHP. But, of course, this means that you also have a fuel pressure gauge. When the car/engine is all done and you've completed the minimum air procedure and reset the TPS and static timing, get on a chassis dyno and fine tune the fuel pressure that gives you 12.8 to 13.0 AFR while in PE mode AKA WOT.

As a starter, you can set the fuel pressure at 48psi. But if you run the car at WOT (before you get on the dyno) and hear audible knock, then increase the fuel pressure until the knock goes away.

I recommend the Holley AFPR.
