i just got this intake from a vender here. i have a c6z so i need the 146202# it was priced the same as a ls3. i get the box, on the outside it has sticker 146202 which would indicate a ls7. opening the box the intake is wrapped in plastic with a sticker that says 146102(ls3) and ls3 install instructions. also the kit came with no intake port seals. their are also no part numbers on this intake whatsoever. i called FAST and desribed the intake and they say ls3. also called my tuner, he says not like any Ls7 he has seen. i thought the intakes ports were suppose to have metal plates with screws in tham? width is about an 1'' 1/2 and height is about 2''1/2. i called the vendor and he says he knows the diff between ls7 and ls3 and its def and ls7. anyway, here are the pics-

The pictures you show are a rectangular port.

I thought the LS3 heads were the heads with the rectangular ports and the LS2 and LS7 were cathedral port? I know my LS2 was a cathedral port.

Have you sent your pics to Fast and asked them which intake it it? I see where you called them and they said it was for a LS3, so If I were you I would return the manifold to the vendor and have them send you the correct part.

With those pic's looks like a ls7 intake.

. I think all this could have been avoided if the guys at FAST woud have put a part # on the intake.
