Charley, the dome pistons you have will fit in the aluminum heads. The intake valve reliefs need slight work if you are using a cam with over .150" valve lift @ TDC.

Ted, it will be very interesting to see what kind of power you can make with higher compression and new cam. Should step the Altered up quite a bit! It'll be fun watch.

Altered!!, I want to see it in that tube chassis fiberglass 57 ford, For you guys that have not seen it, the 57 is a work of art and this engine would make it one very fast door slammer.

Everyone loved Ted Eaton's "Y" block!
Wouldn't you know that after getting our but kicked by a Y-block at the EMC, the first job that came through the shop door Monday morning was a set of 312 heads.

Ted: You, John Mummert & company & your test team have done a wonderful job, congratulations! Since we will have to wait for some time for all the results to be published, I have one question. Since I brought up this subject some time ago, do you recall what your "roll in" torque numbers were? Again congratulations!
Paul

......I have one question. Since I brought up this subject some time ago, do you recall what your "roll in" torque numbers were? Again congratulations!At the competition, the Y was rolling in at 2500 rpms with 363 lbft torque and was peaking out at 477 lbft torque at 4900 rpms. Peak horsepower on each pull was happening at 6500 rpms so there’s still some HP left in the engine at that point. Air density was much higher in Ohio during the competition and that actually reduced the roll in torque values due to how the carb was initially setup and tuned during testing at my shop.

hi ted, again, great job. did you try running some good raceing fuel in it to see what max HP would be for that setup? thanks, wayne.

hi ted, again, great job. did you try running some good raceing fuel in it to see what max HP would be for that setup? thanks, wayne.Wayne. The higher octane fuel question was asked earlier in this thread and here’s the response. Ted (10/11/2010)

,,,,,any speculation on power with better fuel?A different (re: higher octane) fuel actually will not gain anything in the EMC Y’s case. It was already optimized to use fuel from the corner store which means a higher octane will not provide any additional power benefit. A density change in the fuel though would require a jetting change. On the flip side, if the timing had to be retarded to compensate for a lower grade of fuel, a loss in power would be realized. Although the dynos at the EMC event were giving lower numbers than the home dynos the competitors were using (myself included), I was still happy with the numbers I was getting during the competition. I’ll add that some top end horsepower was sacrificed in the tuneup to get an overall better score. Lowend performance and torque was enhanced at the expense of some top end horsepower.

hi ted, sorry, i forgot to ask, how many SBC finnished ahead of the wounderful YYYYYYYYYYY?The question should be how many finished behind the Y and that number is high. Far more finished behind than in front of this years Y entry. Performance of the 23° headed 400 that finished in 2nd place can not be discounted as it was indeed a solid performer but this engine comes out of a shop with a proven track record of making any brand engine run. In the right hands, physics many times does not care what the name brand of the engine is.The February issue of Popular Hot Rodding will go into detail on this years EMC competition and is scheduled to be on the store shelves 12/21/2010. At that point some interesting stats can be figured based on the Y’s official #16 finish.
