A lot of that will depend on how well your carb is tuned. It seems that this becoming a lost art and most people lack sufficient knowledge to properly jet and tune a carb for an engine.

If the carb is good, I'm betting 330hp to the rear wheels using the stock headers.
 
Well what a big let down!! The guy at the performance shop had trouble early on today trying to burn a chip for another mustang and they are not going to be able to get to me 2 day:( I can't do it next weekend cause my buddy has a big race going on, so looks like it will be 2 weeks before i get to go to the dyno, and by then i will have 1-3/4 long tubes on it, so we wont get any before and after comparisons. What do u guys think she will do with headers on. I will keep you all posted as soon as i get some numbers!!!!
