You all seem to know a lot more about mods for TPI than I do so i have a few questions maybe you can help. I have an 87 GTA it has slp runners, exhaust, computer chip, air foil, 3.73 gears, adn SLP cold air intake, on top that i have a 305 Jasper engine with 10k, I was wondering what the next best modification should be, I dont know if i should go with headers, a cam and gear drive or a different manifold. Also is a underdrive pulley worth it. I lose power in 3rd gear thats where im losing the races so im looking for something that will help me there. Some of my freinds say a cam is a good investment, Is there anything else i would need before i get one. Thanks

 

Headers are always a good mod and are easier to install than a cam

 

dont i have to take out the air conditioning to put headers in? got any suggestions on what kind of headers?
