Trying to figure engine rpm's
I maybe am searching for the wrong things I don't know. I have searched all over Google and many forums and I haven't found what I'm trying to figure.
I am planning on swapping a 1990 7.3idi into my bronco, I am going to use a ZF6 transmission out of a 2000 powerstroke.
I'm trying to figure what my engine rpm's are going to run. It is mainly going to be a road vehicle with limited off road use *Hopefully it will see moab a couple times*.
The zf has a 0.72 6th gear ratio, my Bronco has a 3.50 geared 9" rear end and 32" tires. If I swap it right now using all this what will my rpm's be at 55 mph or 60.
If I overlooked something let me know I cant find anything right now though......
