ET Differences Between Varying Powerglide Low Gear Ratios?

Or do the 60' gains outweigh the longer amount of time in high gear?

Background: I currently have a 1.94 low gear PG and I am looking to speed up my 60's. Would a 2.08 / 2.18 low gear be worth the investment?

Thanks,

How much power are you making,and tq. The 2.18 is a pretty weak gear set. I ran a 2.18 in my ss 327 it was about 4 hun in the. 60 ft fasted than the 1.96 I broke it last year but i did run for about 5 years. Lot of thing factor in , weight gear tire etc etc/
