You can get a used set ($50-100) from ebay (but be careful), or if you want a new set i would go with Motive Gears. I heard they are not as noisy as Richmond Gears, and they are cheaper too. For a new set, expect to pay $175-225. You will also need an install kit which will run about $100.

 

Thats cool whats the site?
And i have a few friends who are mechanics and my uncle and some of my dads friends are to do u think they might possibly have and instal kit

...you might be able to find them cheaper, but thats the first site that comes to mind.

 

So 3.42 would be the best ger than right and would it go good with just my regualr 350 tpi becaise i got my 383 priced for 3000 i thought that was a lil steep.

 

Correct. If you plan on staying TPI 3.42 would be perfect. 3.73 is okay but not the greatest for a stock TPI set up opposed to other set ups such as the Stealth Ram, Super Ram, Mini Ram that breath better past 5,000 then 3.73's would be ideal for those type of setups. BTW if you plan on thowing a 383 in your car I wouldn't wanna keep that TPI in there for long you'd be better off with throwing a on one of the above listed Ram set ups becuase as most of you know TPI does **** after 4500 and that 383 would choke to death robbing power.

 

How much would one of those intakes run me i planed on beefing my tpi system up which would be better?

 

Buying a 3:73 Gear Set depends on what Rear Axle you now have on your car. A gear change is Not exactly a bolt on part. My opinion would be to more research on this subject before you jump to conculsions.
