To add to Pauls comment, I think the shaft mounted rockers are unique, any scrub built for performance goes back to this style.

To Me it is the Harley Davison of all v8 engines. Takes a little tinkering, but they always run, are stout, great sounding and will perform.

Doug's comment that the over & under intake ports are the most unique feature of the Ford/Mercury Y-Block engine, is obviously correct. However, the engine is somewhat unique in other areas in total. For instance as far as I know, it was Fords first "side oiler." And I don't recall any G.M. or Chrysler auto engines of that era having the extended crankcase, going right back to the transmission mounting. And there's the semi air gap intake manifold. Then there's the solid mushroom lifters, which I believe were usually only found on some Diesel engines. And full floating wrist pins, which were not found on their nearest competitors engines. And the somewhat uncommon use of an external oil pump.. and I'm sure I've missed something.

Well, i enjoy scrub bashing!! Its our Ford owners divine right and should be made compulsory at school.

Scrub bashing for me is a response to all the years of listening to the lies about Ford performance capabilities. Mostly it's harmless banter between car guys and ranks up next to "mines longer than yours". Some take it very seriously and must be approached with caution. Chuck in NH

I'd guess that the manifold is very beneficial. It looks like it's near impossible to design a dual plane intake for side-by-side ports that have port lengths that are even close to equal. It also looks like the floor of the intake just under the carburetor is always significantly lower on one side of the dual plane intakes for side-by-side ports. That's got to have an effect on overall fuel distribution. With the Y intake, it seems like those factors are all pretty close to the same. I think the only time it is equalized among all styles of ports is with tunnel port types of intakes.

Congratulations to everyone that made this possible. This is one of those threads that I sat down and read start to finish. I'll probably read it again! Congrats again to all of the major players who are working hard to show that the Y is still a viable, strong motor! I can't wait 'til 12/21 publication!

The only really unique aspect of the Y block is the over and under intake ports. Everything else, such as displacement bore/stroke ratio, rod length etc can be pretty much duplicated with other engine designs. So in a way the EMC competition is testing this port shape to see if it confers some specific advantage for engine output.  I don't think the point is proved either way yet.  But it is worth noting that after only 2 trys with two engines the Y is right in the thick of things.  Considering the amount of development time that has been spent on side by side ports probably amounts to hundreds of hours more than John,Ted and others have been able to spend, 16th place is itself outstanding. 

Ted & John and others, what do you think of the over/under ports?   My personal estimation is that it is an advantage in the heads themselves but a disadvantage in the manifold.  Estimating the effect in the combustion chamber is beyond me!

That's exactly why I don't have a favorite brand. They've all been proven. I believe that most failures of a "hated" brand is a type of self fulfilling prophecy. If you're told that Chevys are the scum of the Earth your whole life, the second you own one, you'll do whatever is necessary to prove the point and you may not know it because it's usually subconscious.
