From a conversation about my abysmal crawl ratio today -

Current build:
Torque converter ratio x 1st gear x TC low range x axle ratio
1.8 x 4.56 x 2.488 x 4.56 = 93.12

In 8th gear:
1.8 x 0.65 x 2.488 x 4.56 = 13.27 (which is probably why I can do 30 MPH in low range and where the convo came from)

Compared that to the new rig:
Torque converter ratio x 1st gear x TC low range x doubler x axle ratio
1.8 x 2.804 x 3.12 x 2.7 x 5.29 = 224.91

I may have to learn to drive differently. 🤔
Stupidly, I sold my 1978 Ramcharger in 2014 after 15 years of owner ship. It went from daily driver to trailer queen. Among other things, I put a 4 speed Atlas in it behind the NP435. First gear was 6.69 plus double low of 10.34 plus 5.13 axles came out to 358:1. That was basically useless but second gear in the trans made it 177:1. I normally ran it in single low at 3.8:1 in the transfer case. I wish I hadn’t sold that beast that I named Detroit Steel.

Slow and low.. that is the tempo

14bolt in a Ramcharger?

I got the Atlas 4 Speed for my other project just last week. I went with the 3.8:1 low end though cause on the math I figured lower than that would not be of much use to me. With the 4l60 and the axle gears I plan to use I am around 156:1 crawl ratio. That should give me really good low speed with two other low ranges for less technical driving and sand dune ripping.

You make me miss mine even more. LOL I should have never sold Detroit Steel.
 
14bolt in a Ramcharger?
Yes sir. 14 bolt and a ford high pinion Dana 60. Plus FAST fuel injection and a lot of other mods. She was a beast! I’ve got more pics if interested.
 
Sounds like a cool truck.

I miss my nitrous big block ball of stupidity on 44s but, TBH, the 80 is as much fun and a lot more practical. The old truck was a handful to drive with a spool in the rear on the street and broke every part known to man pretty much constantly.
 
Finally stopped being lazy and got the fuel cooler bracket installed. Truck goes to the shop on Friday for hook up and to address the other leaks I found.

I should probably stop replacing these all the time. I'm betting the weld nut on the housing will wear out from being torqued too often. :rolleyes:

I could always try not hitting stuff, too.

Got a picture of them installed? Look easy enough to make.
This is what I was thinking, as I have replaced that washer and bolt a few time already.
The right size pipe some cut and weld boom done ;)

Just drew something up in CAD - Sending out to be fabbed :cool:
