3.73 based on what my gps was reading and your rpms with your tire size.

your tire calculates out to 27 inches in diameter btw

jack up the back of the car, put it in neutral, and while turning the wheel 1 revolution count how many times the driveshaft rotates.

I agree do the ds thing its flawless

ok, i did check the tire rotation to the driveshaft last night
i looks like drive shaft turns 3.5 turns to one tire turn.
my tires are bigger.
we did a gps run last night, at 2200 rpm i am going 72 mph.
when speedo says 60 mph gps says 70, so 10 mph off.
what would make my speedo read so much lower?

So than u have 355 gears most likely. Mayhe the speedo gear in the Trans is bad?

at 70mph, on a 26" with 4.30s i turn 3100 thru the auto

 

[4valved]

355s then
