Is there any strength difference between the 1.50 and 1.36 gear ratios? Reason I'm asking is building new engine. Around 600hp. Was wondering if spinning a prop faster instead of going big pitch would be better choice to lesson chine walk tendencies. So if my thinking is correct I could keep my eyes open for a 1.36 over the next several months.

600 hp will have a hard time pulling a 1.36 gear unless you go way down in pitch, which defeats the purpose... typically people go to a 1.36 gearing when they run out of pitch in a 1.50....just my opinion

Stick with a 1.50. There is no measurable strength difference.
