Re: 4.44:1 rearend, What's it good for?
Last year we switched our V8-85hp '36 from 4:11 to 3:78's. Went from straining mightily at 55 to okay at just under 65. That'll do for any roads I want to venture out on.

If you are interested, Currie Enterprises, has a tech. page that you can use to calculate R.P.M., gear ratio, tire diameter and speed. I found it very useful!

Re: 4.44:1 rearend, What's it good for?
Are you in the EFV-8 club? If so, I bet you could probably find someone with a rear end to swap. I've dropped out of my chapter here in San Antone, so I don't know when or where the state meeting is. But, it is usually in April. I think that might be a resource to locate the parts you need. I probably have some 3.78's but you would have to get someone to build up the rear for you.

Re: 4.44:1 rearend, What's it good for?
4.44 would be a lousy choice as-is but potentially a very good one with an overdrive.
Possibles are columbia ($$$), '41-48 Lincoln OD trans,($$$) or a mitchell; compute costs and time switching to 3.54's, consider that the OD would give you the benefits of much taller cruse gear WITH the killer low-speed gearing of the 4.44, and it might start looking very attractive. The deep gears plus overdrive would give you a very good gear spread, whereas changing just the R&P can give you good cruising gear but will actually hurt your lower end gearing. This is perhaps a chance to have your cake and eat it too... |

Bratton's Antique Auto Parts, here in Maryland, sells the 18 tooth turtle and gear. The gear is Nylon but will work fine. Bratton's sales people manning the phones may tell you these turtles and gears are for Model A's but don't let that worry you, they will also work on early V8's.

Both my Model A,s have Columbia OD,s with 4.11 & 2.94 ratios & work great with B engines with 5.9 head.Will pull most hills with no problem.

Re: 4.44:1 rearend, What's it good for?
Have any of you guys considered installing a T5 trans ? Cornhuskers ,Speedway just to name a couple offer the adapters to do the job. The beauty behind this is the fact that its a 5 speed over drive.
I'm giving serious consideration for my "37 with an 85 hp. The people that I've talked to that have done this say that it's the sweetest thing they've ever done to improve the driving experience. Rayzor Rayzor |

Re: 4.44:1 rearend, What's it good for?
I just found one in really good shape today on Craigslist, and real close to home! It has back plates, brakes and cylinders, probably '39 -'40. Got it for $75.00 He had no idea what the ratio is, really good deal whatever it is, so I bought it! When I got home I marked the drive shaft end, and the axle shaft, turned the drive shaft spline 3 1\2 turns + a tiny bit, and the axle shaft made exactly 1 turn. Is that a 3.54:1 gear set? I did it like 4 times to be sure. Whatever it actually is, I'm thrilled I found it!

Re: 4.44:1 rearend, What's it good for?
Hard to say. Best way to check is to hold one hub still, turn the other hub exactly 2 turns and count the driveshaft revolutions. If it is a 3.54 ratio it may be a Merc axle. Some pics might help identify it, and some measurements could be useful - length of torque tube for instance, type of hub and brake backplate (at the lower pivot point area).

"Bruce, I had 4.44 gears in my car when I bought it. It's not fun shifting to second gear before you get across an intersection..."
You gotta do the whole package, the way Ford did it on the Lincoln...low rear, closer ratio gears in trans, circa 30% off the top in overdrive! |

Re: 4.44:1 rearend, What's it good for?
I'm learning more every minute, between the HAMB and Ford Barn. Tonight I'll look for the numbers stamped below the torque tube bolts, I hope it is 11_39, but I'll be happy with 9_34 3.78:1. I do know it is '37 - '40 based on these pics.
