383 running rich
383 running rich I just put in a 383 lt1. I am having trouble with it running rich. I put the bosch platinum single prong spark plugs. Could this be the problem? I've hear alot of different stories about them. I have the stock MAF, TB. I also have LT's open for now. I have the front o2 sensors connected and the back two i have sims on them. Stock fuel pump/lines/injectors. Any info would be appreciated

I don't think thats the problem but you should get NGK's or some autolites. How old are your O2's. You can delete the rear O2's with a PCM tune and won't need the O2 sims. How is the duty cycle on your injectors?

Open longtubes with O2s in them will let freshair get up to the O2s between exhaust pulses making the O2s report leaner than the engine actuallty is causing the pcm to dump extra fuel at it.
Do you have it tuned? The stock pump and injectors will not handle an even halfassed stroker.
