Hello, I got a 91 firebird with a 350 .60 over. 2.5 in flowmaster exhaust. No headers stock manifolds. I am wanting some Ideas on what I should or can do to make my car faster. Any help would be greatly appreaciated. Thanks

 

Start with exhaust from the engine back. Get complete mandrel bent system for a single cat TPI car that way you can get 3" y pipe from the headers (brand is not real important) and a Catco 3" CAT and 3" CATBACK (again brand is not that important). Then you need 3.23+ gears and posi. Being a 91 you can run the famous $99 Zexel posi from SLP and get some gears. I am partial to the 3.42 gears. I have run that ratio in several cars and found them to be a great street gear.

 

Thanks for replying. Will that setup work even know I have a tbi setup. Thanks

 

yes it will.

 

any exhaust setup for a third gen will work...82 -92

 

Is it a roller block? If so, I would grab maybe a LT4 cam while you're at it. If not, you're choices for aftermarket cams are endless and already cheap.

 

cams for roller motors arent exactly cheap. Usually about 250$ a pop.

 

Yeah I was tryin to say to grab a roller cam from a factory engine because it can be had for less. And if its a flat tappet cam, then his choices are endless. I was a little unclear in my post.
