I don't want to definitely say yes to the forged internals, but I want to... I DO know that there is a BIG difference between these "3.8"'s and the "3.8" used in so many other later GM cars...the internals and whatnot are much stronger on the turbo Buicks. Hopefully someone will answer the forged question for sure, otherwise, I'm sure the answer is on gnttype.org or turbobuick.com
