If someone could give me back to back test proving hp or reliably/ longevity that would be something completely different, just not pure opinion.
A belt drive can isolate damaging harmonics.
Years ago my buddy had a small block chevy 9 second vega. He started cracking blocks on a regular basis. Ended up That harmonics were being transmitted to the cam causing bad stuff to happen. Don't know if he was running a gear drive or chain at that time.
