4.10 gears? What rpm you turning?

I was told when I purchased the car the only modification to it was lower gearing in the ***, I am turning right at 2000 RPM's in six gear 70 miles per hour, does that sound right? What RPM's are you guys turning with stock gearing at 70 in 6th?

Well then that makes sense, looks like this car does have 4.10s possibly

Marc's chart show 76 at 2K. Wonder if you have 4.30's?

Well it was just a tinge under 2k at 70. The PO said 4.10s

I like the 338mph @ 7500 in 6th with stock gears!

Cool, just remember the tachs on our cars can be inaccurate. Check your tach against a scanner or Tech1. It’s unlikely someone would put 4:30s in an otherwise stock car.

Even if the tach was 10% high, you'd still be over 300mph
with stock gears!!!
