1984 corvette

I have a 1984 corvette 5.7L V8 that is cross fire injection. I was wondering what would be a cheap way to boost the power on the vette a little more.

Power shot for the 84

Glad to see some interest for the so called "Ugly Duckling."
The crossfire was not well known for it's power, but a few small things can be done to liven it up a bit. For instance, disable the A.I.R pump. (If local emission standards are lax.) This means pulling it apart and removing or disabling the impeller, also shorten or remove the A.I.R injectors that protrude into the exhaust manifolds. Change out to a set of headers, gut the cat, and see what happens.

go to the corvetteforum.com, c4 section. they have all kinds of mods and tips, although most are tuned port guys there are some crossfire gurus there. ask your questions and get your answers. dont go to OT unless you have your flame suit on, those guys are brutal sobs. i hang in c4 sometimes but only lurk in OT. those guys are the funniest guys on the net, you will laugh your azzhat off.

My own opinion and granted I'm not up on New Jersey emission rules and regs but if all of your smog equipment is intact leave it. The A.I.R. pump uses very little power and you can get a good set of smog legal headers w/the pump fittings. Doug Thorley (now owned by Pertronics) tri-y's would help the low end along with a good 2.5" true dual exhaust. But that alone won't give you much seat of the pants feel.

At a rated 205 hp for the '84 cross fire any performance enhancements would be welcome. You would most likely have to get into the engine to see any real gain. Like most engines, a cam change and good heads would make a world of difference. But that all depends on how much money you want to spend and how many miles are on the original engine. Nitrous is really the cheapest bang for the buck but that gets costly when you start refilling those bottles all the time. As Techron says the corvette forums would be the ones to ask.

Doc here,

IMHO, pull the mis~..uhhh..Cross Fire.out , mount it on your power mower.then install the Briggs and stratton in the Vette..

Crossfires are like a Bi~polar wife...ya gotta love 'em to live with them..and be ready for mood swings on a dime.
