“Best” all around axle ratio: ~450hp w/ A904?

You should have been in a completely different gear with that big of a change. I.e. with 4.56 I was trapping at 5,200 in OD (GVOD) and with 4.10 I trap at 6,200 in 3rd gear with a 727.

I'm unsure what you think a significant gain is, but if you went from 4.10 to 3.55 with no change in trap gear, trap RPM or 60 ft time it is a little beyond my understanding.
Selective quoting must be inherited from another part of the Forum... LOL...
If you quote the first sentence of my post the picture become a little more clear...
Almost everybody's car out here on the Internet is faster than mine and of course the biggest thing they go to is they know how to tune and drive yet odd that 98% of them can't produce a time slip...
