Default LS6 for LS1 Swap

If I were to swap my stock 2000 LS1 for a crate LS6, use the original MAF, TB, LS6 manifold, original ECM, would it work, or would I be tripping codes and have emissions problems?

Car will run fine. No codes.

You might want to have the PCM tuned to get the most out of your setup..

Is the LS1 stock computer settings the same as the LS6 computer?

Can you run the original injectors or do you need to Z06 injectors?

It should be pretty much "turn key"......may require some tuning.

If all you want is a stock LS6, then procure a tuning package, and transfer the settings from a LS6 calibration. I'd use the LS6 MAF and injectors.

The 1999 & 2000 C5 (yours) used 26.2 lb injectors. 1997, 1998 and all 2001-2004 LS1's (C5's) and LS6's (Z06's) used 28.8lb injectors. To my 2000 C5, I'm adding a Comp Cam, LS6 heads, 2001+ intake manifold (LS1 and LS6 were the same), Supermaxx longtube headers w/high flow cats and X-pipe followed by an LS1 Edit tune. I am installing the later 28.8 lb injectors. I believe the duty cycle would be awfully high on the stock 2000 injectors, though some have successfully used them. I just wouldn't want a failure (causing an extreme lean condition at WOT).
