1000HP from an Iron Block?

**oreowizard** · 03-30-2008, 07:52 AM

I heard of this in another thread. How is this made possible? I heard its a LS2 block, like in a Denali. Which heads, etc??? I may be able to build something like this pretty soon. Just wandering kinda where to start. Thanks for any input.

the ls2 is aluminum and not in any suv's except the trailblazer ss. you prolly want the lq9 which was in the denali, escalade, hd trucks, etc... its iron

i knew it was the lq9 block found in the denalis. What heads do most of you suggest going with? I will be getting a race shop to put it together. Thinking of a procharger or twin turbos.

I am using ported sock ls1 heads but if i had the money I would have used afr heads they come in different configurations but from what I have read they are the best out there for now
