I have updated my cylinder head flow spreadsheet with some new information. I have broken it down by LS1, LS6, 5.3, and 6.0L

If you have flow information for a set of cylinder heads that you'd like to see added, please forward it on. The more information on the heads, flowbench, etc... The better. If there are any features you'd like to see added, please chime in.

EDIT: My webspace went away years ago, so I've removed the link and posted the spreadsheet here directly. Its a very old spreadsheet. But, it should give you some basic info...

 

great info man :thumbup:, this should get a sticky.

 

great info! time to play with desktop dyno

 

link doesn't work anymore. is there an updated list anywhere else (should be since this is 4 years old lol)

 

Here you go, this is from the sticky in the newbie sectionhttp://ourworld.cs.com/jrp98ls1/stockheadflow.jpg

 

link not worky

 

Still works for me.

Just look at the stickies in the new members section if you can't get the link to work. The info is posted in there.

 

worked for me

 

I just checked the sticky and the link is definetly down.

 

Agreed, the link is down for me too.

 

 

some one fix the link

 

I have it saved on my computer at work and I'll be glad to post it up tomorrow. I don't know why it's not in my imageshack anymore.

 

^^fixed^^

 

I can't get either to work

 

You can't see the picture in post 11?

 

yea, I finally got it saved & zoomed in large enough to read.

 

If only flow numbers meant anything...... Choosing heads based on flow numbers is like trying to determine which car is faster by looking at EPA mileage ratings.

 

Which makes perfect sence. Lower fuel milage=more fuel being used, more fuel being used=more power, more power=faster.

 

Right!..... so the '09 6.2L 4wd Tahoe (EPA est. 11/14 MPG) must be faster than the LS3 6 spd 'Vette (EPA est. 16/26 MPG).
