Picked this up this weekend. Never seen one like it. What can you fellas tell me about it? The edge of the intake is 1/2 inch thick. Thanks Bill

I'm no flathead expert, but looks like someone shaved of the generator mount off and made a crankcase breather out of that area. Probably for a race car without a charging system ?

I agree with Sal. I don't have a manifold or catalog to compare it with, but that breather sure didn't come from Offenhauser like that, though the breather itself might have.
 
Ya' learn something every day. Although I find a "racing model" with heat to be a bit odd. The way the breather is attached looks pretty professional. I think the cheesy blue paint affected my judgement.:o

That was Offy's answer to the Edelbrock super dual, They Made two versions, one was an inch higher, and is no longer made. This may bt that unit. I used one on the Bville engine converted to two 2GC's. Yes, I think someone installed a pan breather on the front. Good idea. Probably used an off set gen bracket.
 
99 percent sure the breather is original. Everything looks to perfect a job. I did a quick low pressure glass bead to clean up. From bottom of intake to the top of carb mount is 4-1/2 ". Same as my 8ba offy.

That's what confused me too. I agree that it's an early manifold for racing, since the experts chimed in, but why would it have the exhaust crossover to heat the manifold ? Unless it's plugged internally and Offy just modified a street manifold to make this one.

It it doubtful to me that the front breather was 'factory original'. It would require additional machining steps that I don't think they'd like to do -- or they would have cast that area with the breather cavity and a boss on the outside. Now this is just a wild-*** guess/opinion - not based on any knowledge of any kind! (Like most opinions I guess :))

I have somewhere an old Offy catalog that shows this intake in it. It is an original. Take a look how flat the front "nose" is. Later Offy have a different shape. There isn't enough meat on a later one to machine it down for a breather. I'll try to find that catalog in my stash.
