95 firebird 411 4x swap

[Codyd]

Fellas , working on 95 firebird with golden built 383. Car runs good in OL but when I command CL B1S1 goes Rich and B2S1 goes lean. I?ve done the firing order , injector bank and did the 2,3 an 4,7 injector repining to the pcm. What am I?m missing? Take it easy on me , first one I?ve ever fooled with. Any help would be greatly appreciated.

Post the log file showing it doing the thing. You've only posted some words here. If a picture is worth a thousand words, then a log is... more than a thousand words. I'd bet the O2 sensors or injector wiring is crossed bank to bank.

This might be the "split BLM" problem that GEN2 LT1's have with a decent size cam. You should be able to read about it on google "split BLM"
