8k? Yeah, maybe. It would take cams and some porting and exhaust, etc to pull to 8k. With 315x35x17s at 7200 rpm in third, 3.45 rear gear will get you to 120 ish mph. If you're north of 132 mph + in 3rd gear, I would agree you're rubbing shoulders with 8k. Otherwise, I suspect the tach is off a bit.
I knew my tach was reading high (common problem) but not 20% high! Marc mentioned it and I confirmed with my scanner too - yep - 20%. The tach would run off the scale and then some before the limiter would engage!
So, screw the tach. I did calibrate it, and now it tracks pretty well. But, the shift light is soooo much better for best/consistent shift performance and avoiding testing the limiter, methinks
