That makes sense. H55Fs are pretty long for a shorty 40 and an F series motor (they fir better with a V8 that you can move way up to the front). What ratio are you running in the diffs? Stock 4.11? I had 4.11s in my HZJ75 with 35s, and the overdrive was nice on the flat or downhill, but you could forget about being able to go uphill in 5th. Pretty similar in the wagon with 3.70 and 33s. But it sure was nice to be able to drive to Moab and back and be able to cruise at the posted speed limit for most of the 75 MPH sections.
