Nice gains especially at 7000 rpms. Are the castings US made?

Well I think GPI saif it was the biggest in the vid. But Im sure they can fit a bigger one. And think about a solide roller!!

More cam will make more peak power at a higher rpm. We have been working hard on optimizing the valve events for average power from 3500 up.

We will be doing bigger stuff.

Actually a 233 intake lobe that isnít in that test made about 15 more hp but didnít surpass the 226 till 5800 rpm.

Whammo its on their website on the script under Rhinos script at the end of the post, and anyway YUP LOD has posted nothing though I now a member put one of the LODS on recently and hope he posts.

I know the guy that did the post getting the first set as the mule for these heads was kind of sneaky in acting as if his cam was all that with its high lift but he; was for most unknowledgeable people misleading purposefully as the ls7 heads take 1.8 rockers versus 1.7 for the ls3 so the real specs of the cam are much less than cam for a ls3 with the lift coming from the rockers a lot.

And that is of course a lot with the flow one of the reasons to get the heads to be actually easier on the valve train....a reason a ls7 has a 7k limit, and lower lift cam can make the same high net lift with increased flow/compression what ever you desire and have a different valve angle for PTV clearance and accept a ls7 manifold which yup we are limited to FAST mainly or modified stock or some sheet metal from the net unless its a new LOD speedworks, or such or hack a firewall for a holly high rise, Vararam let us down and so did MSD over the years I know I was here....

The ratio difference adds up to around .035 more net lift from a cam if you know what I mean..... And happily await future dynos of these heads with a stroker and better cams, and await someday to hear more on LOD speed works results also............

Solid roller will make some more power but require re-lashes of course and be harder on the valve train as they are...........now hitting this head with what ever combo with Sauce and maybe FI of course will be so much more because of the FLOW. LS7 heads flow much more than ls3.. thus excellent for more radical builds and they show yes first a video with out ethanol then one 60/40 mix....and they add the MSD intake to that second video, Myself I wonder how much the MSD is worth over one of their ported ls7....I bet its not much and may not be worth it if compared stock ported versus MSD basically one costing four times as much but appearing better with a nice feature.....

Yup still looking for White Rhinos....the perfect heads, the perfect intake manifolds etc....these heads may just be the best ticket for a long long time..... I know I priced comparable five years ago..... this is my second gen 5.

Looks awesome, we have a few L99 cars getting the max treatment. One car being bone stock, which baselined at 339 rwhp.

It will be getting bolt ons and the max package with VVT retained of course and we will document the gains.

Its going to be a potent combo!

The customer is building now. I’d say hopefully in a couple weeks, not sure on his schedule.

Here is the latest update. Our customer with the rock crawler won’t first place on his first time out with the new combo.

Our l99 candidate is almost done installing himself and will be coming back for tuning. His car made 339 bone stock on our dyno so we have a great baseline to start with.

Here is the article on the max package on the truck.

Yep, bump.

Wondering if it's worth a trip to GPI to get it done at the source...It's only an 8 hour drive.
