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.

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

Ted "Y-GUY" Will this engine be in anything at Columbus this year? BillNot a drag race engine but a land speed engine. This one will be in Keith’s ’32 at Bonneville in a week or so.

Ted, extremley impressive figures, what fuel do you run in this? thank you. regards bill. 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.
