THANX!

I am interested in how you do against the 327. I assume they can use a much improved cyl head. Will watch closely this go-around.

Where does one find the actual rules?

This link is off of the Hot Rod website when looking under 'events'.
EMC Early Iron Rules_2019v4 
These rules were recently updated and there are some things in there that changed from the official set of rules but we were told to not worry about the new changes regarding camshaft lifts.   All engines are required to check out at no more than 0.600" lift at the valves when all the lash is taken up.

The cylinder bore is notched to clear the 1.960" intake valve, no issue with the exhaust valve.  We had witness marks with the 2.020" valves in one pair of heads, and went back to the smaller valve heads, and 5/16" valve stems.  Joe-JDC

Hi, how did you get that much lift with iron heads?

It is hard to say how the dynos compare because they had unlimited in the compression ratio rules, and then supplied 100 octane Sunoco GT fuel that detonated 5 of 7 entries before they could establish a horsepower number comparable to the 110 most did their dyno testing with.  I pulled about 4* timing out of my engine, and lost 30 torque, 30 hp instantly, but when adding back timing, I lost my head gaskets, also.  Scott Main seemed to think it was a "bit stingy" compared to his before testing, but he won.  Joe-JDC

Is it far off?

For 2007, I don't remember the results, but ted estimated 375ft lbs.  http://www.eatonbalancing.com/2008/03/17/engine-masters-challenge-y-block-entry/ 
For 2009, it was 440s with the heads being a bottleneck and a lot more ci,  http://www.eatonbalancing.com/2010/03/24/a-y-block-at-the-2009-engine-masters-challenge/
.
Still tough to compare with all of the rule changes between.  Is it over 375ftlbs?  I would at least think an improvement over 2007 since that would be the closest comparison.

Edit:  I see my error.  The 2007 estimate is based on E85, not 91 octane.  What were the results for the very first one to run?  Can't find that anymore.

Hate to post any real numbers until after the competition as the other competitors are likely looking to see what the other contestants in the class are doing.  At this point though, it’s doubtful there much last minute changes going on with the engines being crated up and on their way to Ohio.

With all that in mind, I’ll just say over 303 HP and 257 lbs/ft torque.  I’ll post the actual dyno sheets once the competition is concluded.  It will be interesting to see how my DTS dyno compares to the SuperFlow dyno at JE Pistons.

Joe.  Interesting field of diverse engine entrants.  You and Ted have a 301+-ish C.I.D. y-block? 
Best Wishes!  Have a GooD time!   Smile 

It  will be 3.812 x 3.31 for 302.214 cubic inches rounded up to 303 for calculations.  Any fraction of a cubic inch gets rounded up to the next number.  Joe-JDC
