i was wondering what kind of difference would i expect in performance if i switched out my stock LS3 intake manifold on my 2010 ss? is it nearly the same as a Ls1 to Ls6 intake?

Switch to what? The LS1/2/6 intake isn't going to fit the rectangular intake ports. FAST makes an LSX 102mm intake for the LS3 heads.

thats what i mean.. i havent heard of a lot of people putting aftermarket intake manifolds on the ls3's. i was asking if it would be worth it to do so. it was worth it IMO for the 98-00 fbodies. what gains would i expect to see?
