What's the appeal of an aluminum engine block?

I thought it nice to offer you a "get of jail card", because once you read those facts, there's no further retort.
You're welcome and enjoy your holidays

I'm a statistical analysis kinda guy with real world data, independent and dependent variables, etc. Once you have the study setup with multiple FE engines, both cast iron OEM blocks, Shelby, Pond, BBM, Side Oiler Garage aluminum and cast iron blocks all with the same parts but for the block and related pieces that go with the block and then run them all on the same dyno in the same atmospheric conditions and if the various alloy blocks make a statistically measurable difference in HP, then and only then will I believe it.

Otherwise, just theory, chemistry sets and hot air. Until that happens, I don't want to hear about books and hearsay. No "get of jail card" necessary. Thank you very much.

It's been done before, but not at the same time. Barry has built a motor with an iron block at got x amount of hp. He has defiantly built the same motor using the same parts but with an aluminum block. And got different hp numbers. Atmospheric measure can as well be the same. I'm sure he measures and monitors that when he does dyno pulls. I bet Blykins has built hundreds of FE motors and with the same parts but different blocks under the same atmospheric conditions but on different days. I don't think the idea that it has to be done at the same time means that much. So let's just say it has been done by many builders of FE's. And each time they say iron makes more power.

Seriously, please no more online posts of the cast iron's superiority. They're just words to me. As I said, when available, post a link to the results of the FE engines that were tested all at the same time same place and the exact amount of its superiority. You can get every engine expert in the world to post here, but I want to see the proof at it relates to FE blocks. Not Chevy small blocks or 440 Mopars. I want real world data. And I want to see it.

Ok I have a soft spot in my heart for anal people who want empirical data for proof. I tend to be that way myself.

I did a google search yesterday to see if I could find that proof and failed. However I did find Chevy builders and Mopar guys saying that aluminum blocks make less power than iron blocks.

However I am surprised that you would not accept a test of identical parts in both blocks ran the same day on the same dyno at the same conditions, if the engine was anything other than an FE. Aluminum and cast iron do not care what shape they are cast into! They behave a certain way period. At this point you lost me. This is starting to sound like a real one argument. I didn't say that to PI$$ you off. I seriously want you step back and think about this. I'm not trying to make an enemy. I enjoy most of your posts. I apologize if I did this wrong.
