And, they should make it more competitive this year.

John.   Thanks for the update.  The castings sound like you definitely have something good to work with.  With the Y being allowed to run alongside the roller hydraulic entries this year at the EMC competition, a Mummert headed Y would definitely be able to grab some media attention.

We have machined one of the heads while refining the program. No water was found, which is encouraging. I plan to cut this head up Tuesday or Wednesday to look closer. At this point final valve sizes are 1.94" intake and 1.54" exhaust. I do not expect this to change.

Unported air flow is 235 intake and 180 exhaust. We have done some porting on this head before cutting it up. Lower port tunes up to 250CFM. Exhaust port is up to 200CFM with 1-5/8" to 1-3/4" stepped 90 degree stub. The exhaust flow is very good and should help performance throughout the RPM range.

It looks like the head will be capable of 260CFM intake and 210 exhaust. This is what we expected and probably close to the limits of the original design. This should make a 500HP N/A Y-Block a reality.

More info to come.

Let's hope that Edelbrock doesn't decide that aluminum heads and tripower for Ys would be profitable, therefore decline to cast heads for John, or worse yet, copy his patterns before they give them back to him.  Know any good lawyers, John, just in case.

John.  Thanks for the update.  I’d not be surprised if your aluminum cylinder head project has prompted the reintroduction of the 3X2 intake.  The timeline sure fits.

John,



Good work on the heads, I'm sure your patience will pay off.

My name is Greg and I am addicted to Y's.

We got 2 excellent looking castings from Edelbrock last Monday. Working hard to finalize machining program. Testing program on one of the junk castings from old foundry.

Hope to get this out of the way this weekend and machine the 2 new castings. One will get cut up to check for any problems. If okay, we will give Edelbrock the go ahead. If there are problems we will need to round up the offending core box or match plate and make corrections. This will likely add a few weeks. Things are looking up.

I'm a little surprised to see they will remake 3-2 intake for the Y-Block. They never mentioned that, although they did tell me about the 94 carbs. I suggested they make some "dummy" carbs with no internals since a lot of people only run on the center carb.

John- Any new update? I'm still waiting for your heads instead of buying some 113s and updating them.
