Sounds like a mild blower cam, p/p'd stock heads, boltons, and a p1sc/d1sc. Pretty decent numbers considering only 5 psi !!!
A little more boost and you will make some real power. I know you probably pullied it that way on purpose. Gotta protect the stock bottom end.

97 lt1, 58 k miles. p600b, stock heads p/p, stock bottom end, lt4 hot cam (not my choice) intake port matched, long tubes, msd 6al. It made this power with cutting out right at 5200 rpm, i have a thread in "forced induction" on my problem, any advice would be appreciated.

at 10.5:1 compression i think this is too much for forced induction, i would lower that to 9.5:1 or even to 9:1 compression.
some experts might chime in.

nice mods. i think your 5200rpm power cutting out could be that you need more fuel, possibly aftermarket strong fuel pump and bigger injectors.
at 10.5:1 compression i think this is too much for forced induction, i would lower that to 9.5:1 or even to 9:1 compression.
