Engine/Transmission (1994 - 1998) MPH at 2000rpms

[Justin1889]

What would my MPH be at 2000rpms with a 98 5 speed 2wd with 4:11s?? and 3:54s??

5th gear @ 2000 rpm's w/ 4. 10s = 59mph

5th gear @ 2000 rpm's w/ 3. 54s = 68mph

68 for 3. 54s seems high to me but that's what the chart says. Seems like mine was 65@2000 before I corrected the speedo for larger tires. I now get about 72@2000 with 33" tires and an NV5600 which is just slightly higher in 6th.

Depends on tire size.

Yep, depends on tire size that the truck originally came with (indicated speed doesn't change with tire size change unless it's corrected). I have 245s with 3. 54 axle and I see 68-69 MPH at 2000 RPM.

Here is a calculator if your interested: http://www.f-body.org/gears/

Try this spreadsheet.

It allows you to input your tire size and has tables for the NV4500, NV5600 and 47/48RE.
