8 1/4 diff with 2.45 gears

Just a question: what rpm do you get with 318/904- 8 1/4 wirh 2.45 gears?
1st, Welcome to the site !! :)
2nd, I don't have a tach in my 360/904 with 2.45 gears, but I can tell you it's plenty relaxed at 60 mph, and it's like racing a power glide at the drag way as I can cross the line in 2nd gear :D
