You didn't mention what model your truck was. With a 5.14 I assume it's a 1-ton, seems kind of odd to have a three speed in a 1-ton? I'm no videographer Chaz, so don't expect any award winning performance here. But I did clip my phone to the back of the seat and take ya'll for a ride down the street in my stock '50, 216 with a 4.10. She's a 3604 so her tires are a little bigger than those on a 1/2 ton and should be a little smaller that the 1-ton, which will make a difference. And, she's a splash oiler so I make a habit of not taking her over 3K but like Ken pointed out, that pressure 261 should run up to 4K with no problem and as posted, hi gear in any of the older transmissions is always 1:1 straight thru.
I ran it up to highway speed in the clip, i.e., 55mph which I drive it at all the time. Also, as Grigg posted, if need be I will run her at 65 or 70mph if I have to for short distances just to keep the guy behind me from running up my ars. Oh, and the speed difference on the speedo between the 4.57 and 4.10 is only going to be about 5mph. I would expect, without calculating it, to see almost a 10mph difference if you went from 5.14 to 4.10. So if you're speedo is reading 40, I'll bet you're close to 50. I have a flip phone, haven't moved into the flip finger age yet so if you're still running the 6v electrical, you can still plug a GPS into the lighter socket. I use my daughters old 12v TomTom GPS all the time with my stock 6v system to check my speedo calibration. Denny Graham Sandwich, IL
