Here’s my favorite picture of the engine taken during the exhaust testing.  It’s of the engine with the single exhaust using the crossover pipe on the dyno.  I get a funny feeling that one of these crossover pipes hasn’t been on a dyno since Ford did it’s preliminary testing back in the very early Fifties.  Burned arms anyone?

Guys.  Thanks for the accolades.  Much appreciated.  As far as a book goes, I’m lucky to just find the time to write the regular articles for the Y-Block Magazine much less sit down and write a book.

Chuck.  The chrome pickup headers you sent back with me are labeled as “Tri-Y pickup headers firing order specific-CC” on the chart.  They actually performed quite well.

 

As far as your engine goes, the 471 heads are ported and are currently getting the finished valve work done to them.   Still debating on which way to go on the valve springs but that will come to me when the time comes.  Block work is finished.  The short block just needs the crankshaft balanced and it will then be ready to assemble.

Larry.  The headers in the test labeled as “Shorty 1.625” w/box collectors – DC” are those that David and Robin loaned me when I visited y’all last year.  They were actually the best sounding of the lot and made a considerable amount of noise when the load was applied to the engine.  The difference in sound was quite noticeable from the moment the engine was started with them on it.  Something about those square collectors just made an exhaust note that was much different from the rest of the headers that were tested.

I would like to thank you for another great job of finding and presenting the facts of the Ford Yblock. Mr. Eaton you have done another outstanding job and I am impressed and grateful for all of your hard work. Pete

Larry, I was never able to send the FPT tbird headers as I was busy driving the car!



Ted, thanks for all your hard work this is great reference and like Charlie said what a interesting thing to see what happens when you lose the crossover pipe and step up to duals!

Ted,

I would like to concur with the rest of the guys that we are so lucky that we have you doing all the testing for us and I can tell you it has been very beneficial to me and many of us Y-Blockers.  I saw a post a while back that Alan Frakes had made indicating that he might be sending you  a set of the Bird headers that J. Mummert handles.  David Church has a set he will run on his E-Bird that he is restoring and I have a set that will be on my Bird if we can ever get through with the restoration.

Thanks to You Again for all your work.

Ted,

Is one of these the headers I sent home with you last year? I think they were pickup style. You had once said you thought they would flow very well. Also how is my project going? Chuck in NH

Y's guys rule!

Ted - we owe a lot to you on having all this information at our fingertips. Talk about dispelling myths, etc.

How many of you guys vote for Ted being the next author of a "Y block book"? Obviously, one geared towards performance. In my opinion its about time for another one to hit the mainstream, dispell the myths, tell the real story, and give all of the performance features of the mightY engine we love.

It's good to see 50 years later that 1958 dual manifolds were an improvement on my 56 Ford over the stock single. Not just in my head. And besides that it sounded a heluva lot better. And I kinda think the girls were impressed by the 2 chrome tips hanging under the bumper

The greatest improvement comes by simply fitting dual exhaust. That switch alone accounts for nearly half of the total power improvement in the table.

1 1/2" headers are not nearly as bad as I had thought but it does look like 1 5/8" might be generally the best for street performance.

Excellent work, Ted!



At 10.6:1, is it still on pump gas?
