RPM at 70 MPH
Just took delivery of a 2003 E350 Cargo Van. V10, 4R100, and 3:73 axle. The van has no tach. What do you F series guys turn at 70? Thanks.

Same here. From 1900 to 2100 rpms if I remember right. Seems to fluctuate a bit depending on engine/tranny temp and maybe if you're pulling a slight grade.

HEY MountainHound, how do you like your BFG-285s:-X03

You guys must have huge tires. With the stock 265-75R16's and 3.73 axle, I turn 2000rpm at about 64mph. This is in a 2000 model F250 w/ V10. Maybe the OD ratios have changed?

I have 305/70/16's and it's sitting right on 2000rpm @ 70mph with 3.73 gears.

I have 33" tires with 3.73 ratio, and I am also at 2,000 RPM at 70 MPH.
Good Luck LH |

The last time I went out of town I thought I was running right below 2500 rpm's at 70 miles an hour. Seems considerably higher than everybody else. Get bach w/ ya on this. I'm gonna check it at lunch.

Stock 2002 X 3.73 with the stock 265-75R16's and 3.73 axle, I turn 1900 to 2000rpm at about 70mph.
Was the same as my GM K1500 Pickup with 3.42 gears and 31X10.50 tires that are about an inch shorter. I confirmed this a few weeks ago. |

Have driven three different V10 3.73:1 with 265 (31") tires in the last two years all were right at 2000RPM @70MPH +/- 100rpm
On my personal truck the rpm has slightly increased due to the wear of the factory tires. 2100rpm @ 70mph Torque Converter lock up will account for 175-300RPM difference with the higher rpm noticable when it is NOT locked up (slipping). If you have the 4R100 and 3:73.1 then the only way you are not at 2000rpm @70 is entirely due to some different size tire diameter than 31". Larger diameter tires will cause a lower engine RPM and vice versa with smaller diameter. |

Stock 265's with 4.30 rear end...I'm pulling 2250 RPM at 70.

Yea, I run 34.6 inch tires with the 3.73 and it is running just under 2000RPM's @ 70MPH.
