340 headers?

Desk top dyno is a joke, you can't go by that, I have one of those programs and its fun to play with but thats all. None of the numbers came up at the track like they do on the drag strip dyno. I should be in the 12's according to them. I re-tuned of course, I have an air/fuel ratio guage inside the car and re-jetted the carb, re-curved the distributor, yada yada yada. Its all good, and I am no rookie to this performance thing. I WILL NOT pay $800.00 for TTI headers after reading how they rust, some have clearance trouble if you read some other posts, and maybe capture the starter. Oh, ya if they do then thats another $130.00 for a mini starter. Desk top dyno is exactly what it is, not real world, out in the wind, heat, humidity, track condition etc. I'm done with this.

Funny if Desktop Dyno is such a joke why have I read at least 2 articles in reputable magazines (Mopar Muscle, and Hot Rod) that tested it against true engine builds in the 400 hp range come within 5 hp of what the dyno showed. Are you inputing in all the variables such as head flow numbers, cam timing events, etc...? That makes a tremendous difference. Thogthecaveman has a real good point there. 3.21's aren't exactly 1/4 mile gears. Great for the hwy though. If you look at my very first post where you started your rant you'll notice I didn't try to say you have to have TTI's. Just stated fact that the gain is far more than you say is 15 hp.

Also as far as capturing the starter goes. are they really worse than Hookers? I have Hookers on my Cuda and they capture my mini starter. Theirs no way to get it out without unbolting the header.
