Gear Ratio and RPM deciding on gears
Guys looking to decide over a 3.55 or 4.11 still. Have been reviewing my old threads as well as others. Ran some numbers and wanted bounce off conclusions from this and if I am missing anything. I used the Spicer calculator. Red dotted lines are approximated power band.
1. My 2.71 never makes it into the power band!
2. The 4.56 could hit my rev limiter just over 100MPH say if I was doing the 1/4 mile
3. Not a huge difference between the 3.55 and 4.11 at cruise 70 MPH
What is a reasonable RPM at cruise 65ish for a 340?
Am I missing anything? Does load or type of transmission alter the plots?
Thanks
