Will a 273 rear end gear work good in 454 motor for take off?

A 2.73 rear end gear ratio is generally considered too low for optimal performance with a 454 engine, especially for take-off and acceleration. This ratio is better suited for fuel efficiency at higher speeds rather than for strong initial acceleration. For improved take-off performance, a higher gear ratio, such as 3.73 or 4.10, would be more effective. Ultimately, the best choice depends on your specific performance goals and driving conditions.
