Maybe I didn't explain it well. Let me try this again:
This all started because I was looking at a total Mamo top end for my stock LS1. Everything other than short block and throttle body. That would max out my LS1. I figured that would be around 470RWHP, and be around $7k. At that point, the motor is maxed, and WHEN I decide that I want more (eventually, I will want more), I will HAVE to get a new short block (If I have to get a new block, I might as well go as big as possible so I have plenty of options in the future. Thus a 4.185 bore 440, 451,454). So, $7K now, and later $8k for a new block, and more when I decide that I want bigger heads.
Then I started thinking, if I get a new shortblock and new cam now, I will probably end up with about the same power, but more torque, and I will have plenty of options for the future. I can probably get more compression too (I am going with Flex-fuel so high compression will not be an issue). So, around $8500. When I deiced that I want more, I have a ton of options. Around $3000 up to $8000.
So, I figure that I will spend less in the long run if I get the block now. $11,500 - $16000 if I get the short block now versus $15,000 - 22,000 if I get the top end now, short block later, and end up wanting more.
I never had a goal of 470RPHP. That was just the reference. My end goal is a 4.185 bore motor, and what ever heads/cam I end up being happy with.

Just stating the obvious here, but those are astronomical numbers you're throwing around for a 20 year old car. To get to maybe 600rwhp.
I think a 408+aftermarket heads for $8k for 550rwhp (depending on how aggressive you go) is a much saner bet.
Or just going with a JY 5.3L and turbo kit + fuel system for $7k... and making you know, 800rwhp. The turbo car would be worth more on resell, FWIW.

I never considered a turbo car, since I live in AZ, and the summers are 115 - 120 degrees. This is a daily driver car. I always thought heat would be an issue. I also assumed there would be a lot of fab work to make it all fit. I think I would still want Ductile iron sleeves for a turbo motor.
