Opinions on 4 speed with OD

Wait, how the heck do you come up with “if you run a street gear like a 3.55, then 5500 in "third gear" will be about 124 mph?”
What size tire is this. You assume a bit here huh?
Have you personally done this?
Same with all the other math
This is all gotta be KPH


MPH= (rpm x TC)/ 1056xR1 xR2
(5500x27pi)/1056x3.55x1.00= 124.44718, rounds to 124mph.

I guess
you forgot
"third gear" in the overdrive box
is 1:1

Ease into it Rumble, ease on into it. Your like a meteorologist;
