This year, Ted and I are bringing another Y Block to the EMC.  The rules are quite restrictive this time around, and it will be almost pure Ford Y block.  It is a 292 +.062 and the stroke is 3.310" with 113 iron heads at 10.45:1 compression, Mike Jones camshaft with .591", Mummert dual plane intake, BG 930 DP carb, FPA Thunderbird headers, MSD ignition, belt driven water pump, etc.  We have tried several combination of heads, valve sizes, valve springs, carbs, intakes, spacers, etc., and finally think we have a decent little Y for the challenge.  There will be two 327 scrubys, 2 BB scrubys, 2 FEs, 2 Ford 429/460, Stude, Olds, Buick, Pontiac, 413 Chrysler, 289 SBF. and a couple of others I can't recall.  We are scheduled to run 6th on Monday the 30th.  Any guesses for horsepower and torque?

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.
