Sometimes you can't see the forest for the trees. People seem to always rule out parts as being the problem because they are new and they paid for high quality parts. When in all actuality in the world of high performance, parts hardy ever fit right and have to be modified to fit.

 

Im just wrapping up an LS swap in my Camaro and a brand new AC Delco crank sensor and Rostra cam sensor both failed out of the box

 

Did you have both Parts stuck together like magnets?
