Don't think this is a re-post b/c I didn't come up with anything in my search...but check out this article about the new LS7!

I haven't seen it. Good stuff.

Ls7

 

who's going to be the first to replace their LS1 with one of these?

 

I can't wait for the firts LS7 cam swap dyno.

 

Nice info

 

But does it have VTEC?

 

With heads like that, longtubes and a cam are likely to net you 550-600 at the wheels...

 

same here, i'm waiting for a cam swap
ls7

 

I thought the long, skinny ports on the LS1-6 heads were supposed to be better than shorter, fatter gen 1-2 type?

 

Exactly what I'm thinking!

 

I'm trying really hard, but can't find weight figures for the Ls7. I skimmed over the article, but couldn't find any. Anyone know what the ls7 weighs?

Just curious. I really like showing the OHC (especially import) crowd the true potential of what they refer to as GM's family of "old-tech" pushrod dinaosours of v8's (Lsx's). I'd like to point how how that oversized 7.0L monster of a v8 is actually smaller in size than their NSX"s 3.2 v6, and perhaps even lighter as well. And hell, under normal driving conditions, probably more fuel effiecient as hell.

So the article mentioned that the engine size is physically the same as Gen III Ls1/Ls6, but i didn't see the weight figures.

 

I'm sure the weight is very similar. The only area where there's significant increase in weight would be the main bearing caps.
