I'm in the process of installing a set of LS7 heads on my C5-R 427 along with the new intake. Also going with an LS2 throttle body. My previous heads flowed 330 and I expect the LS7 heads to flow around 380.

With a little luck, she'll be spinning her wheels next week :yeadog:

For those interested, I'll post the dyno results when I get it.

Do you mean you are installing C5R heads on your C5R block ??

The LS7 heads are not available yet. Note that the LS7 heads are based on the C5R heads but they are slightly different.

No DJ, I mean the new LS7 heads. My business is a couple miles from both the GM Proving Grounds and the Wixom engine building facility. I've also done some work at the Proving Grounds.

These are the real LS7 heads :thumb:. I'll have a bench flow done prior to install too.

What are you doing for the intake?
I'm using what I assume they'll call the LS7 intake ;)

That's what I figured you would be using, but there's always the custom sheetmetal option as well. :thumb:
