1933 Model B and V8 drivetrain differences.
What are the differences in transmissions and rear axles for 33 ford passenger cars that were equipped with the model B four cylinder versus the V8? What are some of the other notable differences in the engine compartment and the controls layout. Also, I have a 33 coupe that has the VIN prefix CBT. What does that prefix indicate?

Re: 1933 Model B and V8 drivetrain differences.
Your CBT engine number prefix indicates that your car was produced by Ford of Canada and was built with a four-cylinder engine.
The '33-'34 four-cylinder rear axle had a shorter torque tube and drive shaft than the V8 version. The transmission cases were unique, but the gears, etc. in the cases were the same. The engines and everything attached to them were unique, as were the exhaust system from the muffler forward. The engine splash pans are unique as were the radiators and the radiator support rods. The accelerator pedal assemblies were unique as were the choke and throttle controls. Those choke and throttle controls attached to the face of the dash in different ways. |

Re: 1933 Model B and V8 drivetrain differences.
Thanks for the info. Now I have other questions. At some point in its existence my coupe got a C59A V8 engine. Could the V8 have been transplanted into the car without changing the transmission and torque tube? How do you tell the difference in the transmissions and what length should the torque tube be? Also thought that I had read somewhere that rear axle ratios were different for the model B and the V8.

Re: 1933 Model B and V8 drivetrain differences.
The V8 and 4 cyl transmissions are notably different ,The 4cyl will not bolt up to the V8 and vice versa.On the V8 the starter is on the right and at the level of the oil pan. Only 2 gear ratios were available in 33 & 34.4.11 and 3.54.

Re: 1933 Model B and V8 drivetrain differences.
Here's a photo of a '33 V8 transmission and another of two '32-'34 four-cylinder transmission cases (with '32 rear mounts in this case). The four-cylinder '33-'34 transmissions used the same rear mount as their V8 counterparts only in reverse to accommodate the set back of the four-cylinder engine/transmission assembly.

Here is the difference between the V8 transmission case on the blue dolly, and the 4-cylinder case on the right. The difference between '33-'34 4-cylinder torque tubes is 1-1/2"... not 1-3/4" as someone referenced. Coop |

Re: 1933 Model B and V8 drivetrain differences.
1933 – 1934 Ford Torque Tube Lengths
TORQUE TUBES '33/'34 V8 = 61-13/16" 4-cyl = 60-3/16" DRIVE SHAFTS '33/'34 V8 = 60-5/32" 4-cylinder = 58-7/16" |

Re: 1933 Model B and V8 drivetrain differences.
Wow Coop
CALLED ME OUT.....I guess "ABOUT" 1-3/4 is "WAY" off the mark.....I guess you are not as friendly with Edward Francis & George DeAngelis as I am, being what ends up an 1/8th off on the torque tube measurement & .0315 off on the driveshaft length (Given Trevor's dead exact measurements, Thank you Trevor)......too much to be considered a "slight" difference "amongst friends" (or not). I thought Ed & George's use of "about" gave a little leeway as it "could" be slightly longer OR in this case "could" be slightly shorter BUT thought close enough that IF the OP was or had a rear difff's to measure, whether it was from the top of one of the bolts holding the torque tube to the housing OR from the face of the housing, 1-3/4 is ABOUT the mark........ Super Tough crowd these days I see!!! Lol!!! Last edited by rockfla; 03-23-2023 at 07:06 AM. |

THEY state that "due to the new design of the V8 transmission, the V8 torque tube was longer by about 1-3/4 inches." Well, that just ain't true! The 4-cylinder torque tube is shorter because the 4-cylinder engine block is 1-1/2" longer (front to rear) than the V8 block. So, I wasn't 'calling you out'. I was simply trying to keep things as accurate as we can. Coop . |

Re: 1933 Model B and V8 drivetrain differences.
Very slight difference in ‘32 B & ‘33-34 B transmission cases, has to do with clearance for steady rods I believe.

Re: 1933 Model B and V8 drivetrain differences.
The steady rod difference between a '32 and '33-'34 engine/transmission assemblies in terms of the steady rod attachments is in the upper flywheel housing, not in the transmission case. The '32 upper flywheel housing has separate steady rod brackets while the '33-'34 upper flywheel housing has cast-in holes for the steady rods' attachment.
