Street combo for stock 440

Again.

There is nothing wrong with running a factory iron intake if you want to. Just be informed as to what the differences are. "Disaster" can be a relative term. My whole life was "ruined" the other day because there were no jelly doughnuts.

And

I would be interested in any empherical evidence that Chuck Lofgren may have, on cylinderhead tests made, wherein the only difference between the engines was the material the cylinderhead was made from. With few exceptions, all I see is people proclaiming as truth, things they heard and have never personally tested. This is the reason I have provided the ONLY TWO examples of this type of iron vs aluminum test, I have EVER FOUND. Now granted, I have done no such tests, and have only searched 20 pages deep into those 118,000 references, so I may have missed something on in there. I make no other proclamation other than their results were interesting.

What if aluminum or iron does make a difference?

What if it doesn't?

I don't believe either way yet, but I lean towards it doesn't.

I just tested a 500 stroker with 906 iron heads on 91 octane this past August. 11.9:1 compression, .160" quench, distributor locked at 39 degrees initial/total and not a hint of detonation. It only made 745 HP.

You seem like a bright lad. Your car does run good!

I just think you have to be smarted (smarted? Duh smarter) than the engine you are building, whether you use iron or aluminum.

I wear my iron intake as a badge of honor! But not for long 'cause it's heavy. You bring some valid points to the table and I understand exactly what you are saying. I get it. And I enjoy the conversation because it makes me think. I wish I had the time and money to prove or disprove all the theories when I was starting out with cars but I didn't so I have to make informed decisions based on what I have read, what I have done in the past and what I'm doing currently. It's all a lab experiment with me. Again, original poster's title: Stock short block".

Hmmmm, 745 HP huh? Did you check to see if all the cylinders were firing? :VB toast:

Thanks for all your comments gents, it is for sure an interesting topic and it brings a lot of great ideas out for discussion.

After much thought I think I'm going to run with a 6 pack set-up and a suitable cam/heads. That way I can retain my air grabber and still get a little more bump out of the motor without getting too radical, as this is strickly a street car. When I finally get this together I will be sure to post my results and some pics to go with it..:yes:

Thanks again all !!
