Is this de-tuned 429 worth keeping? 50,000 mi A friend said it could be a candidate for a 671 because of the 8.0:1. I have'nt done any homework on this yet I'm just throwing it out there.

Will the stock bottom end hold if I keep the boost down? More show than go.

The 385 series' bottom end is massively strong.
