Re: Model A rearend conversion I converted my Model A rearend to an open driveline using parts from Speedway Motors as part of the T5 swap.

Re: Model A rearend conversion 1: Potvin, at 60 what are your rpms?
2: What gear ratio is your your end? 3: Is it true that on a T5 first gear is too low, and you end up taking off from 2nd? |
Re: Model A rearend conversion Remember you will need to add brackets to keep the rear end from twisting. My advice would be a later, stronger, rear end if you are going to make the brackets.

Re: Model A rearend conversion I used Valley Machine also, great guy....

Re: Model A rearend conversion Valley Machine Shop offers a brace for the rear end when converting to open drive line.

Re: Model A rearend conversion Some people I talk to say going to the S-10 5-speed doesn't pick up that much, and it's whole lotta work. So how much MPH do ya pick up?

Re: Model A rearend conversion It is a bit of work, but my Model A trans had bad bearings and I wasn't about to do all the work to fix it just to replace it with another A trans. For me, it was about the benefit of having a trans with syncros as much as it was the overdriven 5th gear. Being able to down shift and/or shift into first without stopping completely, as well as the closer gear spread, changed the nature of the car completely.

Re: Model A rearend conversion What many of the people are overlooking is that the Model A is not a car you would like to run all day at 75 MPH. I have a '31 RDPU with 3.54 gears. It is happy at 55 MPH. It will do 75 but at that speed the front fenders act like airplane wings making it very light in the front and susceptible side winds. A good example would be the wind being pushed by a semi or a wind blowing down a canyon that crosses to road. I like it to be my decision when to change lanes. Mechanical brakes are not designed for 75 MPH. The steering and suspension are not designed for 75 MPH.

The takeaway, for me, on the T5 conversion was the syncros that allowed easier shifting around town and the closer ratio of gears between first and fourth. Around town, with the stock box, second seemed to get rung out a little farther than I preferred and third tended to be a little too tall. Splitting the difference with the T5's gearing seemed to helped a lot. Food for thought I guess... |

I have often said over 75mph feels like you have air suspension. With the full fenders, you do! Good Day! |
Re: Model A rearend conversion Our speedster will cruise effortlessly at 70mph with the F150 gearbox and the highest ratio 4th gear, but we only hold this speed on a motorway in light traffic and excellent road surface. Otherwise, it's most comfortable cruising speed is around 55 mph and it's brakes and suspension that dictate that.

Agreed....my point was simply that the engine determined top speed, not the transmission. I'm running a B engine with an original CRAGAR head, hydraulic brakes, F-100 steering box and a host of other go-fast goodies. |
