Royce.  I interpret the rules as allowing the mushroom tappets but not the solid lifters.  I read hydraulic lifters only.  Looks like I’ll have to ask the rules committee for a clarification on this.

Rules permitting, how about a 316 incher?  Last years heads and intake, possibly some smaller sized tubes on the headers with a 3” collector.  There’s time enough now to actually test some other heads.  Camshaft specs would have to be revisited though.  750HP Holley still seems to be the obvious choice.  This combination would definitely have a better score but as you point out, the rules for this year would appear to favor the EFI entrants.

If the rules do not allow the Y then how about a MEL engine?  I’m thinking roller hydraulic for the camshaft.  Unfortunately the rules also require a single carburetor and that’s a serious detriment for the MEL.  I was originally thinking along the lines of using the Super Maruder 3X2 setup but that’s not an option either based on the single carb rule.

An international Y entry.  Sounds very kool    (and the MEL too).

Is there a link to the new rules? I would like to read them over.

Rules sorta make it look like they want the LS1 scruberlays to be more competitive. Pushing fuel injection but can't use 4 valve heads like some of the late model Ford cammers. 3 valve 5.4L Ford should be legal. Last years winner Kaase (Causey) can't run a Ford this year. Their explanation of what fuel injection manifold is legal is very confusing. Sounds like they want a throttle body on a dual plane 4bbl manifold. This will get some clarification later, I'm sure.

Ted, they correct to SAE which is quite a bit lower than the Standard we are used to seeing. That is why numbers were lower than you saw on your dyno.

This sounds like another scrubrolet conspiracy theory to me. They can't win so they have to change the rules, builder, whatever to look good in PHR press.

This years rules calls for hydraulic lifters so a Y is will not be a player in this years competition.  I do have an example of an early hydraulic lifter that is a mushroom design but I’d be hardpressed to try to use these for a performance application.  I’ll post a picture of one of these lifters later this week as it’s quite simple in design but does still requires oil to be routed to the lifter galleries.  Not impossible but simply not worth the effort.

The rules are clear in that only hydraulic lifters are allowed.  For this year, mushroom tappets still remain disallowed in all cases except for the Y.  If a Y can be made to work with a hydraulic lifter while retaining the mushroom tappet design , then it will be legal for this years competition.  The 2010 rules are simply a rewrite of last years rules and the people writing the rules just do not realize that the Y did not come from the factory (for the mainstream engines anyhow) with hydraulic lifters so the rules exception for the Y concerning mushroom tappets is still there.  I don’t have a problem with this as rules are rules.  Was just glad that a Y was able to compete last year and show that they will hold together at 7400-7500 rpms while making respectable power numbers on pump gas and using cast iron oem heads.  While there were two Ford 427 SOHC engines at the competition last year, you’ll likely not see them this year for the same hydraulic lifter rule restriction.  That’s another engine that came from the factory with solid lifters only without the immediate capability for hydraulic lifters to be installed.

Here are a couple of pictures of a mushroom tappet hydraulic lifter.

I think we need to talk to that Argentinian Y block guru who has posted on this site before and get a fund going so he can ship up some parts that would really have the people scratching their heads as to what it is.

Slovers casts an adapter for the MEL to use the newer 385 series intake manifolds.

Or are adapters not allowed in EMC?

Thats a good ideal if they are hydraulics Ill give some for shiping

Hears a link of them the pic of the block does look hyraulic but i cant read a word there saying LOL

It took three years to get the mushroom tappet rule amended so a Y could run.  Regarding rules changes in general, at the conclusion of the competition, competitors are asked for rules changes or amendments in preparation for the next years competition.  That would be the logical time to do a formal request.  But there’s nothing preventing a mass influx of emails to the rules committee in the meantime stating the case that engines that came from the factory without hydraulic lifters should have some kind of exception in order to compete.  Even suggesting duration and lift limits specific to these engines to help level the playing field with the hydraulic lifter competitors might help.   The Ford Y-Block and the Ford 427 SOHC engines are good examples of solid lifter only engines.  If you can think of any other American made V8’s that came only with solid lifters, then these should be brought up also.

The email address for the rules committee is in the rules.  Here’s the link to the current rules.

Weren't the non SOHC 427 side oilers available only with solid lifters?  The hydraulic 427s were top oilers, were they not?

Paul.  Thanks for the tidbit regarding the early Studebaker V8.  If that particular block or engine family was not later retrofitted with hydraulic lifters, then it would be like the Y and a solid lifter only engine.  The FE’s when first introduced in 1958 were solid lifters but hydraulic lifter versions were introduced into that family of engines not long after the engines introduction.

Charlie, which email did you use to send your inquiries too?  If I'm wrong then I need to resend it.

The EMC rules committee have modified the rules to allow engines that came factory equipped with solid lifters to compete alongside the hydraulic lifter entries.  Here’s the excerpt from the Feb 11^th rules revision that gets the Y back into the show.  The letters to the rules committee have obviously been heard and the response was definitely positive.

Ted hope to see ya at the Spring Thaw..Denton TX..

Good to see you back Wayne.  The results of the 2009 EMC competition have already been published in Popular Hot Rodding and the Engine Masters magazine which both did the Y movement justice.  The Engine Masters magazine may still be on the newstands but the Popular Hotrodding piece was awhile back.  Here’s a link to a thread regarding last years EMC competition.

And here’s the link to the first article that was published in the Y-Block magazine.
