Power gains?

[lukendan]

My 69 Charger has a steel crank 440. Fresh motor w/ 906 heads. The pistons are 9 to 1. Heads have a mild port. Edalbrock Performer RPM intake w/750 CFM carb. Cam is bit more the stock. I have also just put caramic(w/ inside and out coat) TTI headers and TTI 3" exaust w/ "X" lead pipes.  What horse range should I be in, and how mush gains should the headers and 3" exaust give? Thanks in advance for any info.

sounds like a nice street combo....i would say approx 400hp & 440 tq @ the crank of coarse..........

I would say that's pretty big exhaust for mild 440 you have, youre probably losing a bit of low end torque with that big of an exhaust. How big are header primaries?
