Let's move this from "New Member Into" to "LT1 Based Engine Tech", where tech problems are discussed.

You need to tune the PCM for the grossly oversized 50 #/HR injectors. Why would you put them in an engine with a HOT cam? Stockers would be fine. If you still have the stock injectors put them back in.

If you want to keep the 50's, get a copy of LT1_Edit for OBD-1, and tune it yourself. Or get a mail-order tune from someone like pcmforless:

PCM for Less

And stop driving it.... the excessive fuel is bypassing the rings and washing the lubrication off the cylinder walls, and diluting the engine oil.
