Those Running 3.73 And a TF w/ LockUp.. What's your highway Driving Like?

to be fair, i was a lot younger then. but i still wouldn't hesitate to get in the warhorse and do a california turnaround to pretty much any NA point today. currently the tires are 26.5 so it brings the R's down to a "reasonable" level. i'm not saying it's perfect, but it's about the best compromise. also, i don't care about laying rubber, ET & trap speed or trying to hustle some crap can one stop light to the next on friday night.

3.55's with 25" tall tires was a level of: i can stand this for about 2.5hrs, but super fun in town with a deep 1st 4spd.

anyway, the 46 has the same gear spread as a 727 and the OD is .69 so you'll likely want something in the 3.9X~4.1X ratio in that a 4.1X would effectively become 2.8X at cruise.

a 3.7X with the right tires might put the cruise RPM in the 1800~2200 sweet spot for a G3 hemi tho.
Just read up on 8HP70.. Final Dive isn't that much different than the 46. 8th gear is .6667 (first is 4.6957 lol)
