I got a 87 305 tpi, Ive got a xr258 cam for it, ported plenum,air foil, headers,6al, rebuilt 700r4 w/2200-2400 stall, bfg drag radials on back everything else is stock. 2.73 gears wich I would like to keep for highway use. whats my next step I have @ 300 to spend whats the best bang for the buck IYO....thanks.

 

You looking for go fast goodies?
Ok something for looks?

 

Look to a torque arm and lower control arms. This will help with your launch. I'd also recommend getting some subframe connectors to help with stability and longevity with the car. Just my two cents.

 

You cant beat nitrous for bang for the buck. Just dont get stupid with it.

 

I know you want to keep your 2.73 gears, but going to 3.08 is not going to hurt your fuel economy that much, and is going to give you a much better acceleration. I am running at about 1900 rpm at 60 mph with my 3.42 and my 5 speed. Just my

 

set of 3.42 gears gets my vote.

 

400 hp hit the nail on the head. Your car won't suffer economy that much, go with the 3.42's this is where to get the bang for your buck. Just remember if thats a 10-bolt which I assume it is you need to buy a 3.42 thick gear set to keep your carrier.

 

exhaust...

 

Nitrous is fun but there is something about a bad@$$ suspension and great handling that gets addictive. Remember, it will help launch and cornering.

 

My '91 305 TPI was a bore to drive. So I altered my air cleaner assembly and attached a K&N air cone, switched the slow 2:73 gear to a 3:42 and alumium '98 Camaro drive shaft. BIG difference car now then before. Minor cost, about 500 and change. Andrew

 

hello!!! the guy needs headers and a 3" catback. without those any other mods wont perform up to par. the exhaust is the most restrictive part on any thirdgen.

 

I know I know, sorry! But I did the other first. I will continue when I get back to work on mine. Andrew
