California Emissions on my 56?

That is what was throwing me off Sal. Valve was located down at end of manifold and not up at the top as would be for a crossover. I found out tonight I have a 312 with a 292 crossover with a exhaust valve in a 312 location. I even went as far to see if I had an exhaust hanger at rear driver side to tell me I had duals at some point, hanger is still there yet I have single exhaust out passenger side.

I it is indeed a truck engine, then it's not a 312. No 312 was factory installed in any truck, including a F 100.

I thought all 56 V8's came with dual exhausts or dual exhaust type manifolds ???

At some time in the past someone put on whatever leftover exhaust parts could be found easily.

Not too big of a surprise considering the number of years since '56.

If it was a crate motor, the 292 truck engine was the engine that the rebuilders were using back in the day to replace the old 239's and 272's.
The air cleaner looks like one of the era that was used on the 4bbl teapot carb from what I can see in the photo, but yours appears to be a dry type. To my knowledge, Ford didn't switch to a dry type until 1957 and it looked completely different from yours. I may be wrong about whether or not they offered a dry type in '56 though.

IMO ONLY ...

(...and this is after determining any amount of engine blow-by) (as the ventilation system on it has been fabricated)

I would suggest the PCV System from a later 60's 292 truck engine. It is tucked out of sight and functional.

Also a 1957 292/312 intake to accept a later style HOLLEY (unless you want to retain the teapot - nothing wrong there) and defeat the LOAD-O-MATIC feature. This is done by using a 1957/ dist and modifying the 4000. A PERTRONIX II will give it life.

And of course, for the proper sounds effect, it HAS to have duals...

Have the glass tinted so as all cannot see your big smile as you cruise...
