4.10's without question. I had them both. The 3.73s lasted about 1.5 year, then went 4.10. MAJOR improvement. I also eliminated lock up converter, and it still not bad on the highway. Sure, it wouldnt be my first choice to drive cross country, but I take it on 2-3 hour trips on the highway with no problems
I can cruise 70 mph around 2500 RPM
