My local Chevy dealer is willing to sell me a complete LS3 crate engine for $5500 and I was wondering how difficult it would be to swap the engine into my LS1 equipped 2002 Z28. The dealer explained to me that the 58x reluctor wheel in the LS3 will create a problem with the oxygen sensors because the LS1 uses a 24x reluctor wheel. How would I solve this problem? Any suggestions would be greatly appreciated.
