A single turbo 408w is my dream build, but it's un-attainable while I live in an apartment, and it's not a smart build to do on a convertible anyway, so while it is my dream, it's irrelevant. I was just making small talk.
While it might be the correct block, to verify both that it is and that it is viable in the build up of a ~300rwhp engine, I'd have to pull it, strip it, and send it to a machine shop to have it magnafluxed, bored over. And then, it might not even be viable, might find something wrong with it. That's time and money wasted.
Whereas, if I buy a crate engine, I can have it delivered, pull the current engine and swap in the new one in under a week.
So, it's quite possible I'll spend less money and time by going that route.
On the other hand, let's say I pull the block, have it machined and it's okay, I still have to pay 800 for a good bottom end, and 2700 for the Trick Flow top end, plus the same amount of money for tuning and everything else.
So even if it goes PERFECTLY with the stock block, I'll end up spending 3500 dollars, and my car will be out of commission for a month or more.
I'm just not seeing the upside of using the current block.
