    So I have a 1997 GTP and I'd like to do the 3.4 pulley swap, but I know I have to do a couple of things first so I dont mess up my motor. I already have exhaust so thats out of the question, but what is recommended/needed in order to do the 3.4 pulley swap?

    thanks

    it's all explained there. and if the exhaust you speak of is just a cat-back, you're not helping much. the front manifold tends to be the most restrictive. happy modding

    96 Firebird Formula - T-tops and exhaust leak. 14.26 @ 97.8 - sold

    you can do it for about 600 bucks IIRC. use the search button for discussion on headers vs. PLOG downpipe, which brand headers, which tuner, etc... there are more threads on that stuff than anything else on here.
