Someone doesn't like the Y-Blocks winning two years in a row with aluminum heads so they are not allowed this year. If theY's win again this year out goes the stacked ports too.

Rules:

I was thinking something like that might happen.  At least it is only aluminum heads that is not allowed.  They need to make it appealing to others and having only one vintage engine that can win does get boring from other perspectives.  This should level the playing field and make it more interesting, at the expense of impressive hp and tq numbers..

At least the Oldsmobile folks can't use the aluminum head, either.  I believe the - G or 113 heads can be ported to be competitive with a bit of valve work and they do allow pushrod tubes in Vintage Class.  Interesting.  Joe-JDC

That wouldn't work because the rules specify OEM cast iron heads.  I wish the SBC could compete in vintage, just put a limit on them so they can't use Vortec heads, or some other good modern OEM iron head.  Make it so they have to use a head from the same period as all of the other engines.

What about mating Windsor or Cleveland oem-heads with Y, custom intake, custom camshaft and custom everything else? Smile

That wouldn't work either.  From the rules "OEM cast iron cylinder heads are the only type of heads that can be used. Heads must be originally manufactured for the engine application in which it is being used."

I have been able to get the lower ports on the iron heads into the 250+ cfm range, and the upper ports into the 264+ cfm range, which is capable of making over 500 hp in a 340ish cubic inch engine.  I still believe that it is possible to get close to 550 horsepower with a larger engine and be competitive in scoring.  I would like to see a real Y Block make 600 horsepower, NA.  Maybe Ted could do it with his 401????

It would be awesome to show up with an iron headed engine and still have a 500+ hp entry.  That would very likely win and people who question the potential will have nothing more, that is credible, to say.

Teds last iron headed entry did put out good numbers but at that time, I think it was ci limited by the rules.
