Thanks man. Did you put a T5 brace for the tail section? I read the same thing about it being 50/50. I’m on the fence but will likely fab something up.
I happen to disagree in regard to .86 on OD. I have a different truck though. I have a '46 with a '54-'62 235 (lubricated lifters and higher compression). My T5 is a '95, and I had a guy in WA convert it to mechanical. I plan to use the OEM speedometer. With a Muncie 3 speed, at 3000 RPM it literally sounds like the engine is blowing up. I have a 1352-216. I believe it was rebuilt, but it has the older syncros. I'm replacing with the newer fiber style. However, I'm replacing the rear end with a '55, since my '46 has a torque tube and the '55 has an open driveshaft. I have done the math and .72 would tax my system too much. All of our mileage varies, and I don't have mine fully converted yet. EDIT: I used a Jeep input shaft with 10 spline so I could use the OEM clutch. I have an adapter plate to go from Ford bell housing mount to Chevy pattern which is in my 235. To make it even more complicated, I'm using the original 1953 flywheel and had the 6 volt starter rebuilt as a 12 volt. There a difference in flywheel teeth matching to starter pinion. My '95 T5 had a 26 spline input.
@@bluetube61 I agree, it's a complicated picture for the most part. I am pretty sure I'm running 205/75R15, I have 6 lug 15" wheels. These are close to the same diameter of the OEM bias ply. I have radials on mine. Yokohama Avid Touring tires. Anyway, I'm not done so maybe it won't run properly. But I'm pretty sure after I get done with it, it will be humming down the highway, smoothly.
@@bluetube61 FWIW, I replaced my ring/pinion with a 3.38:1 set which I got from Joe Mendola at Mother Trucker in AZ. He used to hang out on the H.A.M.B. The previous series, including the '41 and '46 is a 3.55:1 and Joe sells those also, but those sets are copies of OEM Chevy ring/pinions. Those are the ratios that Chevy offered on their trucks. These are the gears in my 1352-216 T5. CS/MS MS/CS (37/21)*(32/14) 4.03 1st (37/21)*(37/21) 3.10 2nd (37/21)*(36/22) 2.88 3rd (37/21)*(21/37) 1.00 4th (37/21)*(25/51) 0.86 5th CS = Counter Shaft MS = Main Shaft EDIT: Just for clarity, the 37/21 is my input/4th and why 4th gear uses the opposite to achieve 1.00. 4th gear is always active, hence why each set of gears is multiplied by the ratio.
Exactly the info I needed - thank you!
Thank you thank you very helpful
Totally awesome advice
How do you figure the overdrive if your transmission does not have that tag?

Not yet but I will be. Link to a universal bar in description
I see the link for the jeep input shaft which is a 10 spline but you used a 14 spline ?
What about a sticker that’s on the trans

Everyone needs to give up al the numbers in order to understand the whole picture. What is your differential ratio? What is your tire size? 🤛🏼
@@bluetube61 I replaced the ring/pinion with a 3.38:1, there was a 3.55:1 option on the '46, but in '55 they offered 3.38:1.
