3000 Stall too high?

Keep in mind that stall and flash are different.
Stall is all relative to tq and hp. Is very possible something that "footbrakes" at 3200 behind a 340 will tighten up behind a 416. As long as the vertor companies know what you are up to and cid they should be able to nail it on the first shot. Most will give a free adjustment if you arent happy. They can build a tight, med, or loose 3k, all will act differently. Too loose burns up top end/mph, too tight and its easy to push past the brakes and go red.
Have seen more than a few ptc's go up like hot air balloons behind mid to hi 10 sec 416s. Had much better results with either fti or turbo action units.
Everyone has their own preference i guess.
