Default LS7 Head Flow Results

I posted this in the C6 section last week, and forgot to post this here.

We have had our hands on some LS7 heads.

And here is a build-up of a C5R block with them:

I understand the skepticism. Just ask Bink or J-Rod whether or not this legit.

Joel you the man. It has been really crazy. I tried getting in touch with you several months ago, but never heard back. I had been working on some interesting VE tuning theories, but I think most it of it all just theory.

Hope your bad boy is still running strong. You still running that manly bumpstick?

I had some OutLook email probs last fall?? Ended up flattening my hard drive and lost everything. Did you try me at the house?
Did you test the VE theories?
I didn't realize how busy you've been. Very productive!!!

Still running the 239/251 - how do you think it would do in an LS7??

Yup jealous about sums it up. hmmmmm

damn are you going to have fun with those. Keeps us posted!!!

Hmmm I now Jesel makes roller rockers for the c5r. Would those work on the ls7 heads so you could run a roller? If so, for the track I would do a 388 and spin her up using the flow of those heads.

Unfortunately, they are not my heads. But, I did get to see them and touch them. I was able to compare them against some GMPP LS6 heads and stock LS6 heads. All I can say is WOW!

As far as the rockers, the initial setup will be stock LS7 rockers particularly due to the offset necessary to accomodate that giant intake valve.

Yes, I have been very busy. We have a couple of "Top Secret" projects getting underway plus I am working on a new combo for my car (may get to test some CNC "racing" ports ). Should be interesting.

Sent you a PM.

I can see how the ZO6 will be making 500 rwhp out of the factory. Nice numbers

What do you think there going to cost and when are they coming out?
