intakes 300-500 depending on if i buy used or new.
speed density kit since i believe my tuner prefers it.

now if i do fuel;
injectors 1k
fuel pumps 300/400
flex fuel kit id buy used since theyre 700 new and it's literally a couple line, wires, and a $90 GM sensor.

OEM threshold is about 650wtq for engine and tranny. passed that you get bent rods and clutch slippage.
