( quote from article: we are not going to be so cocky and say we Wouldn’t have made more horsepower with more compression with aluminum heads )

That’s because they would have. Thats kind of the point with running aluminum heads. They’ll tolerate more compassion than an ion head.

But to each his own, its all In having right combination with CAM being key.

You are correct Marcella did‘nt do the build, Chirs U ( sp ) did but it was Marcella top end ( his old Pro Port heads ) made 995 hp. on pump gas.

My advise to anyone with no experience ( first time ) pushing The compression envelope it’s a consult with the experts. Because picking the right cam is key.

Marcella did the heads and intake, you know, the most important power making things in a engine. The ones that take the most expertise in doing correctly. Those and the cam are the heart of a engine.
Marcella, S Brown and Chris U, the usual suspects all doing their thing.

And Scott Brown had nothing to do with it. Keep trying, you'll get something right eventually

The build was over a year ago, even I couldn’t remember all the details, I had to go look. In that thread I give Chirs my opinion on cam, what I thought Pontiac’s like. Turns out I was wrong go figure. Chris made cam choice change. Thought I was helping. Marcella had his input ( I think on LS ) lube swap. Can you imagine making 1000 hp...actually 995 hp. Well close enough on pump gas with E-Heads.

DRAGNCAR ...I never like that guy...LOL wink.

Fwiw i was 10.8 on my pump gas engine and made just shy of 900hp, and i wouldn't want to push it any more than that nased on my experience.
What CI motor did you do you have?

"nased on my experience" I believe you when you say that. Could not hang past that.
You know that cam I am selling came off of a 12.5-1 engine that did not detonate on 93 octane right ? Rod bearings looked new I am told.

Good to hear that cam worked. Post a dyno sheet from it or an et slip or pics of the nice rod bearings.
Why push it to 12.5:1? Did it make more power or run better than my 10.8?

Troy is "in the know" he ran 10.8 once (and windowed his block) we are fortunate he shares his wisdom with us... He is the real deal. He is so good his brand new cam he is selling didn't detonate in a 12.5:1 compression engine that evidently never ran!

For the record, yes more than 11:1 can be ran on pump gas but just because something can be done doesn't mean it should be done.
