Model B engine questions?

Anyone know much about these motors? I found the differences between them and A motors, and i found that the four banger hop-up guys prefer them over A motors. I know they were used from 32-34. I just came across one, are they worth much? Is there any difference between an A trans and a B trans?

Thanks for all help,
Chris

 

b and c motors have bigger rod and main journals , pressureized oil system, counter weighted crank shafts ,fuel pump, hot cam than stock a's ... but b and c are also prone too cracks in valve seat then a model a block.

I may have been lucky, I paid $200.00 for a B engine back in October. The A & B transmissions are different, but you can cut the back off a B pan and bolt on an A bell housing and then attach an A transmission. The B to A swap is very easy to do.

 

Politely, softly: there is a search function here, it works pretty damn well. You should play with it and become friends with it (Hey! not that closely!).

Well i did do that to be honest, I guess im really looking for opinions on keeping this motor, and the value of it. Like i said i found all the years and specs. I looked on ebay and hemmings also, and cant seem to find any values for the motor.

 

I had heard that there was never a model C engine. That was just what people called the later models.

 

You're right Rand, never was a "C". The C on the cylinder head probably confuses people.

 

hi 33-34 more commonly called C motors use same block and crank but have differnt lower pulley, timing cover , and shorter water pump then the b"s

The numbers on this motor are ground off, is there any way to tell what year the motor is? Is it true that only the 33-34 have the balanced crank? What about the lighter flywheel?

 

The "C" is just an easy way of stating that the engine has the counterweighted crankshaft. There was a shaft with press on counterweights that was in trucks but too heavy for race car motors, sometimes called a BB crank. The serial number is stamped on the bell housing not the block. The year doesn't really matter, the type of crankshaft does.

 

If there are not cracks in the block you got a great deal! These are fun motors with tons of low end torque and not a lot of rpm. Max rpm around 2800 to 3000 on the highway with a short burst of two up to 4. Keep it, run it and have a ball. Just be patient with all the old farts who come up and want to talk about it and all the kids who don't know what it it!
