Had a hunch!

Mods are black wing intake, BBK intake manifold, ported tb, LG 1 3/4 no cats and a axel back car made 332rwhp looking to get a little more maybe 350 without opening her up. Any suggestions.

Unlikely unless you throw a 50 or 100 shot of gas at it. The stock motor should handle it pretty easily and you'll be amazed at the difference. However, be aware that you'll find yourself filling that bottle often...
Cheaper than other options but an option that you continually pour $$ into.

There are things you could do to get a little more power out of them but they are not really cost effective. An electric water pump would free up some power. A fast intake over the BBK would pick up some power but these are pretty expensive and not cost effective for a minor build stage that you are currently in.

for comparison, my Yank 3,800 (single disk) flashes around 5,200
