Hoosier Hurricane (2/5/2010) 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, that exact same thought has crossed my mind also probably along with jonn m, lets hope all goes smoothly, cant wait!!!!

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.

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.

Thanks for the update John, looks very promiseing. Looks as if my engine simulation using Engine Analyser Pro and the AFR 165 sbf heads may be realistic. These simulations using a 214 in-224ex on 112 lobe center cam with about .525 lift produced in excess of 350 hp with a very mild engine. Really looking forward for delivery of my new heads with a few clean up pointers as I know you will be busy delivering heads for a while.

Thanks for the update, John. It sounds like great progress. I know you have too much to do, but It would be interesting to me to see the cutaways, if you get a chance. I may never own a set of these, but I'm an avid supporter of your work and the promotion of the Y. Good on you for staying after it.

New head pic.....I'm posting this pic with John's permission. I visited with him and got to watch (get in his way for a few hours) while he machined for seats and guides. Also note the casting numbers, with a bit 'o paint you could fool the puriests! Thanks John ,for all your work on the Y and for letting me hang around your place. Barry L in M

It's all the little details. These heads and a Blue Thunder intake, both painted will make for a fine sleeper.
