Engine plays a role.

ears ago I was racing a Tbird Turbo Coupe down I25 in my 86 Daytona. At 125+ the engine could not pull hard enough in 5th to keep the Tbird behind me. Drop into 4th and I'd pull away from him.

But in all honesty there isn't a legal option for me to need double overdrive. Also, consider I drove my 64 300 from Memphis to San Diego with 4.10 gears doing 70 for most of it, so rpm does not bother me (A745 three speed in it).


They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.
