1999 ls1 manifold and pcm

[70Uglybird]

I have a 1999 ls1 pcm $110 shippedBare intake manifold $120 shippedAlso have a pair of exhaust manifolds from same car I'd have to check on shipping. Supposed to fit 2nd gen swaps.

I can verify that the 99 exhaust manifolds will fit 2nd gens.

Thanks for the confirmation!!! I thought I had read where a guy tried all the Fbody LS manifolds and the 99's were the only ones that really fit.

From what I gather all the 98-02 manifolds will fit, but the 00-02 need to have part of the flanges ground down on the passenger's side.
