Far more race oriented than the OPs street ride. many, many runs down the track to prove it.
You can not get enough air into the cylinder with his heads and cam to make power to 6K, not even close. Past 5500 RPM the piston is going down faster than the flame is pushing it.
Its a tq monster, use it and you do not have to worry about needless wear.
If I let my engine go past 6K on the 1-2 shift I am near 7K at the stripe and the car slows down.

Nothing you just said has anything to do with his combination Again his combination is safe to 6000 or less.
