Lots of pretty aluminum on that engine stand. That head may be the running for the longest exhaust rocker arm ever! Can't wait for some dyno or on-track results.

Not any info on combo, but along with pics said 4k hp. I’m assuming turbos application.

They say they’re looking for 4000 HP. Would guess it is for them and not for a customer but who knows.
I’d say a roots blower. Has a burst plate on that intake. Arias Chevy Hemis have some long rockers. Brendan Murry used to run them in his front engined nostalgia T/F car.

I hope I'm wrong but I foresee valvetrain issues. That long alum rocker probably won't be happy for long

I don't see much Pontiac there. Big money and tons of time. Hope it does all they want and more

Is it perhaps for the Gasser Brothers? Didn't Dil have KRE building him a hemi?
I would be more concerned about the shortness of the intake rockers than the length of the exhaust rockers. KRE claims almost 1" of valve lift possible, but that would put the roller end of the intake rockers almost off the sides of the valve tip.

At least someone is doing stuff like this.

All the hemi heads I've seen have long rockers like that.

The length of those exh rocker arms is frightening!
The only time I have seen rocker arms close to that long is on a 2 cycle Diesel that had exh valves and was never spun up to more then 1000 rpm.

Seems like there was a thread here on the Gen 3 block the hemi heads are bolted to?

According to Jeff, screw blower, 50+ boost.
25stevem, look at those Arias exhaust rockers. That’s an all out Nitro motor. It’ll be fine. Let’s wait to see how it runs. Don’t think they can dyno 4000+ HP.

Pic of Dill's engine from the 2021 thread.
This new engine, put some twins on it and see what you can do. |

They post dyno day Friday results often. Looks like they’re aiming for a new ET record.
