19Cutlass94 Posted March 1, 2007 Report Posted March 1, 2007 exhaust, u-bend delete, dp, 3500 Inake MAnafold, larger TB, FWI or CAI, cam, headers, PCM tune, I think I got the big ones. Is a stock 3500 manifold better than a 3400 manifold? Thought i read somewhere they were worse. Also i know a ported 3500 is the way to go and to add a 65mm TB 3500 plenums have a 65mmTB stock... and yes they do flow a little bit worse stock, but once ported its a difference story. They also make an adaptor for the TB so you can mount a bigger TB, i.e. the 3900TB Quote
