    That's why I plan to take it to the AMP track in phoenix, AZ to learn how to drive it in a more safe environment At least safer for other drivers.

    You MIGHT get 100k miles out of a built block if you're lucky.
    Do you mean forged internals? What makes you say that?

    In short: yes. I won't go into the hairy details, but blocks with forged internals are typically built with looser tolerances to accommodate for the CTE. This allows for increased slop in the components especially at warm-up.

    I agree with Zax. If you have ever heard a built motor at a cold start up you will know what he is talking about. Will it take more abuse and have stronger parts? Yes,but it not built for longevity. It will wear the piston rings much faster. There is a reason you don't hear people with built motors getting over 100k miles on them . Honestly a stock STI block with cryotread internals & coated pistons/valves and a mild head port job would be a nice setup.
