I have a 1969 440 six pack Super Bee that has a new 523 stroker in it with factory exhaust manifolds. I built the car to somewhat F.A.S.T. standards as I like my cars to maintain a pretty much stock appearance. I have not yet had it to the track but it certainly "feels" like it will run high to mid 11s. The factory HP manifolds are not going to be a limiting factor for those kind of times.
That sounds like what I am interested in. Pretty much stock apearing but significant power upgrade. What heads, intake, compression and carb are you running?
