Charlie had posted a link in the prior thread regarding the rules but they're now buried deep in the middle of the thread.  To keep the rules where everyone can access them easier, I'm putting them at the start of this thread.

Ted: Am I correct that the rules as I read them, will require you to get a variance re the 312 crank c/w 292 main journals?  I know there is a lot of enthusiasim on the site for the project, which I applaud, however as I see it, the big stumbling block is that many of the competitors will use "aftermarket heads."  This fact could unfortunately end up puting the Y-Block near the bottom of the scoring. Assuming that 25 engines satisfactorily finish the test, being 25th won't do our cause for the engine any favours. You mentioned being able to squeeze 1.6 H.P/ inch out of the engine. What about Torque figures?  Any comments, anybody?..

I think a naturally aspirated if possible 400 + HP y-block using some old school and any hi tech knowledge would look Great and show just how Great the engine was, and still is. And put to rest some of the garbage the other side had always said,these engines could'nt breathe and make HP. Lets put the LIE to rest!!!!!   Go for it.

Dove was suppose to make them and hopefully there still working to produce them shortly. If they do come out there's no reason I can see to not use them in the test because the other engines I believe use aftermarket heads. With Teds ability and knowledge I'm pertty confident he can put a KILLER engine together and break the 400+HP mark even with our current stable to choose from. I think a bunch of us should help as much as we can be it loan what parts we have if he can use it and help monetarily where we can.

I covered most of these thoughts in the prior Engine Masters thread.  Yes, the rules committee would have to approve the 292 main size on the 312 crankshaft but reading the rules closely, the main size would be allowed.  If not approved, then just go to plan B which is to use a 312 block and start from scratch.  I mentioned that it would likely take a 1.6 peak HP/inch value to actually win this thing but I also made note that the best I can get out of a normally aspirated Y is actually 1.3 HP/inch.  As far as torque goes, camming is the key here and I’ve got some ideas on how to get that torque up high in the lower rpms and keep it there through 6000.

 

After seeing the number of engines that actually fail to make it through all three pulls, I likely doubt a Y would be at the bottom.  Besides, if accepted, this would probably be the only engine with OEM heads which in itself would be a novelty.  It would be nice if Dove had their aluminum heads ready but it would need to be available reasonably quick to work the kinks out of it in time for the competition.  The key here is if the engine can still make 1.2-1.3 HP/inch values, it might just wake up the aftermarket to making some heads and other performance items for this engine that may never come about otherwise.  Even by just showing up the Y can win.

 

The first order of business is the registration and I’ve yet to hear from the rules committee or find the registration form on the net.

Ted:

Don't let the main bearing diameter issue kill the idea.  I align bore 292 blocks to accept 312 cranks.  I know you prefer smaller diameter bearings for less parasitic drag, but at least this would let the engine compete.

John.  Thanks for reminding me about the potential of align boring the 292 blocks to the 312 main bore size.  This would eliminate having to locate a 312 block that would clean up at 3.810".  I'm only hung up on this particular bore size due to having a wide selection of rings available for it.  I'll definitely include this option on the plan B scenario.

The registration form is now available and I’ve got it in my hands.  As an FYI, the registration date has been pushed out to March 31^st while entry selection has been pushed out to April 31^st.  If my current 314 shortblock is deemed not suitable, then another combination will be in the works.

The actual competition takes place in early October so the engine would basically need to be together and ready for dyno testing no later than early August so that dyno testing on this end could be accomplished in a timely manner.

Ted,
I spent some time on the phone with Earl at Dove yesterday. The flow figures he gave me on the protoype Y-Block heads they did would sure help in the challenge. They are not into production yet as you know. This could be the reason to get them to move this project to the front burner. It would help you with the Challenge and give them HUGH EXPOSER for the new product.
I told them to gear up and I would buy a set. Earl told me that you and Mummert were first in line.
Give them a call and work your magic..................maybe we can get them to at least supply you with a pair of protoypes for the competition.

Jim.  Thanks for getting with Earl at Dove.  Maybe this will help to put a rush on doing something with heads.  I'll also give him a call and touch base with him and let him know what kind of time line We are dealing with in the event a Y is accepted into the competition.  The timeline for a new set of heads would require them being available much more quickly than just working over OEM iron heads so that teething issues and development could take place in a timely manner.
