Default speedo question

Ok this might be a really stupid question with a really simple anyone can figure out answer, but its flying by me. What the hell is the redline at 55mph for on a 93 5.0? Agian srry if its really dumb but its been racking my head for awhile.

do you mean 5500 rpm? thats because too much HP and the 302 will twist and actually crack in half, which is not good, they have special braces you can buy and do a rebuild that have a dyno test of 9000 rpm on the 302 block.

Are you asking what the RPMs are at 55MPH on a stock 5.0? i would say about 1500 but cant remeber since i got gears in mine and my RPMS are higher then a stock would be. and i am sure its different from an AOD vs. a t5.

No, on the speedometer there is a redline at the 55mph mark. You know how every mark on the speedo is white well the 55mph mark is red.

no 55 is considered to be the most fuel efficient speed, and that stuck with the manufacters since the 70s fuel crisis!when they dropped the speed limits down to 55, and they didnt come back up like other countries, we have the lowest speed limits in the world and the cheapest gas doesnt make sense!
