Does a 408 require a new front and valley cover? My buddy just got a new 408 and it came with a new valley cover and a front cover with some sensors and a harness. I thought only the LS2's had this. His stock valley cover won't fit but the front cover will. there are also no knock sensors in the new valley cover.

The 'cups' for the knock sensors are hitting inside the block. The back of the block and vally cover don't match up either. The front of the block says 6.0L so I'm clueless.

will have to check the numbers on the block. I'm pretty certain this is an iron 402 (instead of a 408)with 6.0 liter heads instead of ls6 heads. I think he got the wrong motor. This is par for the course. We've both had nothing but problems with 2 differant big name shops this year.
