Well, when I put the Flowmasters on the car, it seemed to loose power! The question is, when I have the headers put on tomorrow, am I going to loose more power? Dyno2000 is making it sound like I will gain 20tq and 29hp!

Thanks :)

switching from stock manifolds to headers you will increase between 20-40hp (depending on header). :) you might need to play with the carb again.

I agree w dark 7068. My car 3514bbl had 2bbl headers on it from previous owner(one of many surprises). With the proper headers installed, it would barly idle it was so lean. Get your headers installed and start experimenting w jetting on the carb.
