Also paying for all the machine work and sleeves and custom one-off parts is just insane. (Figure ~3-4 times the cost for a smaller displacement engine

I do not see the 3L block having "hot spots" on the cylinder walls either. Not with the casting process, material, and design.
If you want to go forged then I would run the 9:1 slugs (9.25-9.3 for you which is even better IMO!)
It sounds like your power goals are in the 400 range too so that is another big reason to get forged.
OK, I will stand here and proclaim this post as the "I told you so" post when someone drops a ton of money into a 3.0L and pushes the boost up and cracks a block. Until then, I guess I'm just a quack 
I never said that the 2.8L was the cheap way to go. Why do you and other jump down my back on this issue? It's not like I am trying to convince anyone, I'm simply stating what has been done in the past and what is possible. I'm personally building up a 3.0L because I know that it will never see more than 350hp.
Perhaps Keyser would like to chime and explain why he decided to take the 2.5L over the 3.0L on his current project?
