I want to improve my engine on gas, performance and speed. I DO NOT want a super/turbo charger. I already got headers, k&N filter, hood and airbox. My engine is 350tpi 92 camaro. I thought about performane chip but i have no clue on what brand. What else?

 

heads and a cam. The stock heads and cam really restrict power above 4500 rpm. That should give you a good amount of power

 

Then unless you want nitrous, YOU ARE on the wrong forum.

Read the description below the forum name.

 

the intake is very restricktive too, port it out it helps

 

Look at tpis.com. They have alot of good stuff to offer.
