HI GUYS

I Have a 2004 silverado with a 5.3L motor . I'd like to know what year corvette style manifolds will fit on my motor . wasn't sure if the older style off the 5.7 would fit or work . thanks

 

ls1 or ls6 manifolds...

 

Are they actually beneficial over the stock 5.3 manifold?
I've got the original LS1 manifold that came off my 2000 Z28, would it be worth installing on my '03 5.3?

 

no...do a search man...type in ls6 intake, and see what you come up with...the truck intake flows better than the ls1 intake, the ls6 is the better of the threee but you won't see any gains "supposedly" unless you go over 6200rpm...do a search dude
