[M&M]

I've been tinkering with the governor in my turbo 400 behind my 455. Got it shifting at about 5200, maybe 5300 rpm. Factory tach, don't know how accurate. Is that too high for a stock bottom end? Used to shift at about 4500, wondering if I got carried away. Doesn't feel like the power is falling off yet, just concerned about the revs.

Thanks
