well after thinking about it and talking to more people im even more torn. finding a decent GN motor doesnt seem easy and im not looking to rebuild a motor in 20k miles. people who had GN's said the turbos caused alot of issues.
im starting to lean more toward the idea of a 350. because for $4500 i can have:
Chevrolet Performance 350ci/330HP HO Turn-Key Engine
