Good news!! We passed inspection and have plates!! So another one is back on the road!
Anyone know what size bolt is the rear license plate nut? Can't seem to find one looking in my parts stash....

Max speed depends on max RPM, final drive of tranny (4 spd = 1:1), gear ratio of axles (4.11?) and tire size.
Jason,
As far as the front plate, I used one of these which will clip on to your winch roller:

Now let's see some pics of the beast, you drive her in today?

I have a 3 speed , so the rpms climb pretty quick. I haven't done the math yet, just wondered if someone knew off hand.
A true 31" tire would have a circumference of 97.3 inches. Convert to ~0.001536 miles.
Multiply to find out that 3000 RPM in that scenario equals a little over 67 MPH.

I've seen lots of holes in the side of F motors because people thought they could drive that fast ... just saying.
Tucker
Okay, if you decided 3000 RPM was max for your F, and you had 4.11:1 in the pumpkins, that engine RPM would turn your tires 729 revolutions per minute if the tranny were in a final drive ratio of 1:1.
Good so far?
Converting minutes to hours equals 43740 Rev per Hour.
What size tire do run? The most accurate answer will require the true size, not advertised.
Circumference of a circle = Pi*D, where D = diameter.

Thanks TJ, very appreciative of the math!! I dont anticipate 3000 RPMS, I dont like to hear the engine whine.
