Topic: 5W model B

  I'm getting ready to make an offer on a Garage find Std 5W Coupe 4cyl. Car is 99% complete and original never molested and unrestored. Question, is it realistic to convert to 21 stud engine and drivetrain? I have 25 year collection of 34 parts but few 32 parts. The car has been stored in garage since 1960's so I don't know if 4cyl would run. Opinions welcomed.

  I would keep the Model B engine myself but since you asked the following changes need to be made when replacing a Model B with a V8 (21 stud, others will require a few more things):

Of course engine, motor mounts
Muffler and exhaust system before muffler (same after)
Radiator
Radiator support rods
Engine steady rods
Hubcaps
Starter switch (if it is early B with pull starter, later ones used the V8 starter switch)
Transmission (gears interchange but cases are different)
Choke (B is a cable, V8 is a rod)
Accelerator linkage
Engine splash pans
Gas line needs to be routed from right on Model B to left on V8
The B will have a few extra holes in the firewall pad from mounting the 4 cyl engine snubber
Need to add emblem to headlight bar
Need to accept the fact that the serial number (VIN) is for a 4 cylinder

Interesting to note the increase in value for the car is about the same as the cost of making the change

  Thanks Charlie. Is the drive - torque tube and rear-end also in question on a swap like that?

  The rear end is the same in 1932 (although the ratios may be different) between the 4 cylinder and the 8 cylinder. I realize there was a difference in the length of the driveshaft between the 4 and the 8 in 1933/34 and I am sure that is why you asked. I would put a 3.54 rear end gear in it if I rebuilt it.
