Are you talking about the new Iron LSX block from GM Performance?? If so, those things are rated at 2500hp.....

Cast iron with 6-bolt, cross-bolted main caps the AWD cadilac come' with it.

Its an iron 6.0 block, same as the Ls1 except for being iron and having a larger bore. I've seen them handle quite a bit of power, north of 700whp.

Thats the one. Do you think it can hanle my 1,000HP goal. beacause my LT1 sure didnt. I need to know because it plan to buy a block this week!

Are you talking 1,000 flywheel or to the ground b/c they are two totally different ballparks. It might be able to survive flywheel, but if your gonna spend that kind of money, you should probably get an LSX. But I wouldn't get in a hurry on ordering b/c I believe the LSX's are backorder like a mother.

Dame its just i messed up my LT1 that I was building up and Im looking for a block that can take it. If the LQ9 cant handle the 1k on the ground (RWHP) then I wont use it. the LSX blocks are back orderd till like next year. lol and they are too expensive. Im looking for a strong block that can take 1K to the ground.

Well, if the LSX is too expensive, I don't know what to tell ya. You gotta pay to play and 1,000 to the ground takes a ton of money. There's the LS7 block, but I don't think it can handle that kind of power.

I got a budget of about 15k. I know its expensive to get to 1kHP but it seems that 1kHP is about 30k buck's. I got the turbo system to buy as well. Im just trying to keep cost down if I can.

My engine builder has told me the samething. Im trying to take it one step at a time. Block first, then Internals then Heads, then the Turbo System. So he tells you whant 1kHP then start off with a Dart block and have 30,000 buck's.
02-05-2008, 11:02 AM #17
Well on an LS setup, block first means consider holding the heads down too, and you aren't likely to hit 1krwhp without a block with 6-bolt heads. 14-15K will get you the long block you need, but you will still need the turbo, piping, and accessories, the mega $$ fuel system, tuning solution, and a drivetrain.

I think that if i go LS ill spend more than if I use a diffrent motor. I just got off the phone with my engine builder and he say's to back down on my HP goal and take a look at 700hp b/c he say's 15k is too little for what I want. he say's that if I do go LS I will spend alot more. I dont know were to go right now.

700hp is than you probably will be able to use unless this is a drag only car, I have a feeling you'd be plenty happy with 700.
02-05-2008, 08:05 PM #20
A 6.0L iron block will handle 1000rwhp fine and will work as a street/strip car. What internals you use will matter as well. Over 1200 I would look at the LSX or warhawk block.
