someone did a really long thread about this, he got his manifold bored, his throttle bodies, sanded where both manifolds meet. did not gain alotta power
Whats "a lot?" I ask because everyones different. Take PPE coated headers in 304 for example...those are close to $2000 vs others or less coating or metal etc. what do LTH's produce? 20/20 max and less at redline on a before and after stock car only?!! Much less vs catless or other headers already on the car. So best/worst case $100 per 1hp? On a car with TP's you might get 10hp. Now you're $200 per 1hp. Portings proven good gains in my book for what you spend, around $78 per 1hp. And CBE's are the worst in my book. Great sounds! Little power, huge price tag!
I'm glad I chose to scrap the headers mod because after becoming full bolt on (except headers and pulleys) the best bang for buck is force induction. I had my fun na. Now it's time for boost.
