Parts over here cost about 3x - 4x more than in the US, that's why I import almost everything (not a joke! I had to pay $50 for a AC belt + PCV valve)

Compression is fine for all 8 cylinders, I didn't had the chance for a leakdown test.

I'd like a new engine like the LS3 but it's not legal to install more powerful engines so in case of an accident I'm in troubles with police + insurance (not that having a blower like the last few years is better, but at least I can remove it and go back to stock in few hours).

It would be fine a rebuilt 98 engine that would fit the existing PCM + harness. Are you guys even rebuild those old engines? Or swap them wir newer ones?
