Here are the dyno results for a 343” Y using a set of Mummert ported aluminum heads.  It’s a 343 incher by lieu of a 3.810” bore and 3.76” stroke.  The compression ratio is 13.25:1 using Diamond popup pistons designed specifically for the aluminum heads.  The camshaft is a symmetrical Isky grind with 263° @ 0.050”, ground on 108° lobe centers, installed at 106½° intake lobe centerline, and 0.592” lift.  The rocker arms are Harland Sharp 1.6:1 roller tipped units assembled on Verne Schumann shafts.  The carburetor is a Holley 780 cfm dbl pmpr which sits atop a 2” tapered carb spacer and a ported Mummert aluminum intake.  Spark plugs are Autolite 3923’s gapped at 0.035” and using a MSD distributor and ignition.  Click the link for the larger version of the dyno sheet.

Not a drag race engine but a land speed engine.  This one will be in Keith’s ’32 at Bonneville in a week or so.

This engine was tested using VP 110 octane fuel.  This is obviously not a pump gas engine with the compression ratio being that high.  On a cubic inch basis, this engine is handily outscoring the EMC engine and the compression ratio is responsible for much of that.  The aluminum heads sure makes that power much easier to achieve.  The torque band on this engine is equally impressive.

Another great job Ted!. It will be interesting to see how fast your Y-Block can push Keith's 32 down the salt.

Ted, I keep re-reading the sheet,mighty impressive to say the least.

I think we will make some believers in the y block @ speed week.

John, thanks again for getting the heads & intake to Ted in time for Bonneville.

its not how fast you go, its how you go fast.

That's what I need in the Uni next year.

Man that is pushing a lot of Horse power out of 15/8 headers. Great job.

Too blown away to comment Ted!

man, that's impressive. sorry i couldn't be there with you keith, but i'm hanging on every report i get. go keith!!!!

If it's not classified information, are you running 2.0" or 1.88" rods and what length?  If that is privileged info, I understand.  Just wondering about how you arrived at that stroke.  Is that the maximum practical that can be achieved in a Y-block?  ("Inquiring minds and all that.")  Congrats on a very stout piece.

Rod journals are 1.889”.  Rod length is 6.300”.  Maximum stroke thus far with a Y on my end has been 4.000” so the 3.76” stroke was relatively easy.

Damn, sure wish I had thought to print this dyno sheet to take to Panama City with me.

I don't have any idea. Exactly for what purpose is this dyno sheet used?

trueman: It's was a test & reference information for the engine of a Salt Flats/Drylakes race car..
