I'd agree, the LS2 is a better bang for the buck, but the LS7 heads are nothing short of amazing. It's incredible that these heads are a factory produced item.
It won't be long and you'll be seeing 500+ cubic inch motors based on the new LSx block with LS7 heads. There's no doubt they will make 700+ hp N/A.
Any feel for whether the LS-7 will come down in price once the LSx becomes available?
When the LS-2 came out, was it pretty expensive as well?
When the LSx Block comes out this month, do you think that the fact it is iron will hurt it's desirability?
It seams that the ultimate, "Hot Set-Up", is a Twin Turbo, because:
-Very Streetable
-Makes hellacious Power
-Can get good Milage
Problem- Very Expensive
I've heard many times that once you get past 575 RWHP or there abouts, the power can't really be used effectively except in a drag racing application. So just about any power above and beyond that, would be just for bragging rights.
My goal would be to have the positive characteristics of the Twin Turbo, up to the amount of, "Real Usable Power", without the expense.
The aluminum Block and Heads are also a big plus for the money. Are the LS-7 Heads better flowing than the top of the line AFR or Trick Flow heads?
The "Magic Bullet", as far as I can see would be something like this. Bragging rights is all that would be lost, as if an engine like this would be something to be ashamed of! ;-)
The fact that the lsx is iron makes me not want it. I am planning on using an ls2. If I was going for 2000 HP with twin turbos then I would want the lsx. ls2 is plenty strong for your power goals, and less weight on the nose.
