Hot Rod posted a nice You Tube video about vintage class, prominently featuring the Y block crowd

The announcer was a little bit scrub! He couldn't help but put down the engines even as they blew his mind a bit. Made the MEL sound like it was the only time a Ford won at the nationals and like it was this big surprise. And John Kasse would have done better with the extrea 500rpm (that and his home made scrub heads). Take out the occasional wise crack and all in all very impressive. What happened to the Poly Mopar? Looked like a new window in the block.


Y's guys rule!
Looking for McCullouch VS57 brackets and parts. Also looking for 28 Chrysler series 72 parts. And early Hemi parts.

Actually Jon's camshaft was done by 5600 rpm last year, and he struggled to make the three good pulls.  Where his engine shined was the torque was monstrous at 3000 and stayed up most of the pulls, which brought his score up.  Joe-JDC

Question for Ted
Curious of the difference in tune you found in the tri-y's opposed to the 4 into 1's
And just clarifying you ran a 375 this year?
Not a 400cu ???
So you had an extra 500rpm, though kasse had an extra 25cu !

Not Ted, but:  Last year the pulls were 3000-6000 rpms.  This year the pulls were averaged from 3500-6500 rpms.  Still averaged the pull for 3000 rpm total, just moved them up the scale this year.  Camshaft makes all the difference in the rpm in which you make torque and horsepower.  Ted could have made pulls last year to 7000 rpm with his entry and made a lot more horespower than was posted.  Jon could not have with his camshaft.   Lots more to be said, but I will let Ted answer any specifics since you addressed him.  Joe-JDC

A 401 cubic inch Y was the original plan but Carrillo dropped the ball on the connecting rods that were being made for this combination.  By the time I had switched to Cunningham as the supplier for the rods, the lead time for a finished set was going to be too late to have them here in time to assemble that engine for the EMC competition.  Joe Craine offered up his 4” stroke crank and Eagle rods which I then used in the already machined 401 block to make a 375 incher.  This allowed for the same bore as the 401 engine but instead used a shorter stroke than was initially planned.  The connecting rods in the 375 engine were ultimately shorter than originally planned for the 401 engine but still worked out well.
 
The 4-2-1 header design decreased the top end horsepower but the gain in lower rpm torque numbers more than offset this to increase the EMC points score.  The key to this competition is keeping the emphasis on the average HP and TQ numbers and not so much about the peak numbers.  The score is calculated using the sum of the average numbers and those are divided back into the cubic inches.  Peak numbers are great for advertising but in this competition, they are not the money numbers.  The headers I used in last years’ EMC competition were making much higher peak horsepower numbers on this years combination but the 4-2-1 headers had much better average numbers; hence a higher score.

Hot Rod has added another link and video for this years’ winning EMC Y-Block.  This gives a bit more detail on the engine and is a precursor to the article that is forthcoming in Hot Rod Magazine.
