And again I don't think the GVOD will fit. I have trouble fitting bigger than a 3.5" driveshaft, theres no way I'd fit a GVOD...
So with a 28" tire and 3.54 rear end, if your rev limit is 7500, then you can go 176 mph at 1:1 Ratio. Problem is with an auto you will have 3-10% slip at that point, so your top speed goes down significantly. And I know you are extremely limited with your ratios, having been down the r200 road before myself. Maybe time to bump up to an 8.8?
I run a 28" tire, and a 3.27 ratio 9" in my Z. Cruising on the freeway at 75 is totally reasonable. Turbos make it quite quiet.

I can do the 70mph 2800rpm thing. What i fear is me running out of gear and or wrapping the engine to the moon everytime i get on it. Also im still considering a 408

At 7000rpm you literally have ZERO slip (Calc top speed of 164), thats pretty amazing. What is your converter?

Being able to put down big power on the street or track consistently and laying down serious times without ever worrying about something breaking let's you overlook other stuff.
Make the car quiet enough and you dont know the difference between 1500 and 2500 lol. I can't unless I look at the tach
Its all give and take

Man all this gear calculation BS is making want to keep my Damn T56 super magnum. I thought the built 4L80E was going to be an easy drop in and go. I never factored in that OD wouldnt hold up at WOT and 3rd gear runs out around 165-170MPH

Also its gonna cost you a massive amount of money if you want it to last a long time with the power you want to run...

Thats pretty impressive. How is spool time on it? I think your setup was similar to my old setup. (At least our times are extremely similar)

That cruise is difference between 5th and 6th gear in mine.
My previous engine/box setup only had 5 gears, and yes rpm's were much higher and it was never a bother. But after having that nice tall 6th gear, I really wouldnt want to go back.
I would really like a proper sequential box, but I'd lose that tall 6th gear with that too...not something I want to sacrifice.

No heat in the system here either.
The converter really works good on more power, the track time was on 18psi, after an injector change and 24psi on the street it was really working good. Not enough power in and it tugs it good on the shift though

I'd call it a magic converter lol. I have a monster turbine, 111mm, here is how well I can get on the brake with a converter that is that tight up top
