Resized all the pictures in this thread to make it readable (especially for Patrick! Figure if it was big enough to bother ME, it'd be KILLING him! Hahaha)

That's going the other way around.

I was saying that:
Al heads with tiny chambers + dished 3.1 pistons = a good 9:1 (ish)
Iron heads with big chamber + dished 3.1 pistons = {who knows but it'll be low!}

Or take a 2.8 block with it's flat tops, plus 3.1 Al heads and tiny chambers... should stick you around 12:1? More? Ha! Who knows - never bothered to do the exact math. But if a stock ~80cc chamber nets you around 8.9:1, a 28cc chamber has GOT to be high!

Iron Block + Alum Heads + 20cc Dished Pistons (3.4L Alum Stock) = 9.3 (with .020" worth of milling)*

Iron Block + Iron Heads + 20cc Dished pistons = 7.3 (With .020" worth of milling)

Iron Block + Alum Heads + Flat top pistons = 12.9 (With .005" worth of milling)

*That .020" worth of milling is necessary just to get 9.3:1, and brings the pistons within .006" of the head (Which is BEGGING for trouble).

Never shift into reverse without a back-up plan.

I use a freeware program called 'pixresizer' and have had no problems.

Not sure what your issue is, but you might want to try it.

The nice part is you can do multiple images at once.

I've posted here about the following free utility numerous times...

It has been my experience in many forums that posting images no wider than 800 pixels works best within the confines of a thread.

I use IrfanView to quickly resize my images. Works great.

Try it, you'll like it.

Did you see the top post on this page? John (Dr Fiero) re-sized all your HUGE images. That would explain why the "user name an another set of numbers" are now different.

Snow Man, save this JPG image to your hard drive and then let's see you upload it to your next post.

We need to see if you're uploading the images properly without worrying/wondering if the file itself is somehow incorrect. We know this image file is fine for uploading (as I just did it).

Okay, we now know that it isn't necessarily the actual JPG image that's causing the problem.

When you try to upload an image from your computer to post in this forum, which icon are you clicking on? It should be the tree with the "up" arrow, the one that says Image Upload when you hover your curser over it.
