Good morning all...
Well in my 194 search ( with in a reasonable driving distance )for my 31 Independence I stumbled upon a 1933 207ci.down In Tenn.
  I'm having the seller take measurements as we speak , but has anyone ever done this swap ?   Will the Bell housing mount up to my original 3 spd trans.  Is it longer , shorter , etc.
Thanks Gents.

In my Cast Iron Wonder book by Floyd Clymer, I found that the 206 replaced the 194 in '33. The main difference is that the stroke was increased to 4" from 3 3/4" Valve size is also bigger but they use the same head gasket. The starter was activated by the accelerator. Iy is the first year of 14mm spark plugs. There was a better carb and distributer with vacuum advance. It says heads can be swapped and so can manifolds and carbs. More inches is better. Longer stroke gives mote torque. There may be some little things but I say go for it especially if it is a good complete engine at a fair price.

Nice to see some "inliner" talk!

   Sixball did that engine not have troubles with breathing. If memory strikes me right it had 3 intake valves and 4 exhaust valves.was that not the problem with the 181 as well. and for the differences in $$$$$$would you not be better off going with the 292 truck engine or the 250 car/truck engine.As a mater of fact if you could find a 261 Pontiac 6 cylinder that in my opinion would be the way to go...Just another guys 2 cents worth  vette59jdwl

Awesome ....
Thanks Sixball.
That's some well appreciated info.
It's an all complete 207 for a fair price just a little bit of a road trip from STL.
  I would go to a larger 6 but I'm wanting something close to the era so it can plug into my original trans without having to change anything else.
  Thanks again for the info.
I'll let you know how it goes.

I have never dealt with a Chevy 6 older than the 216. They always had 2 valves per cylinder. They     had, as far as I know, 3 siamesed intake ports and 4 exhaust ports. Yeah, breathing was not their strong suit but they were less restricted than the Ford flatheads either 4 or 8. All Chevys were OHV something Ford did't get around to until '54 and they still didn't breathe as well as a Chevy.
