Sorry for the long hiatus, the rear end i believe is 10.25 with 4.10 gears, I'm prepping for the ZF5 speed conversion, and Russ Type4 if you can repost some of your old install pics it would be appreciated.

70 MPH at lower RPM
thanks for info, i'll have to take it out on another drive and verify my RPM again. Hope it's just shorter gears and not excessive slippage.- Ray-Ray

70 MPH at lower RPM
I'll be opening the pumpkin and see what's installed, could it be a case where the previous owner installed a shorter gear like a 4.73 or even shorter?. i suck at ring and pinion math but i'll do what i can (ring tooth divided by pinion tooth or vise versa). if i understand it correctly, the GV...- Ray-Ray

70 MPH at lower RPM
The GV works in my opinion, i can feel it shift to OD at about 45MPH. also that's one of my "i think an issue" is it shifts fairly hard coming out of OD. i email GV and still haven't got a reply. what exactly is a "healthy" RPM for these IDI's? i could just be thinking there's an issue when...- Ray-Ray

Recently bought an 86 F250 2WD ATS Turbo 6.9 Diesel with 77,000 miles on it (not sure if it's a roll over miles) and I "want" to reach 70 MPH on the freeway with lower RPMs. I was going about 55 MPH at close to 2000 RPM and last time i did try to drive it at 70 MPH the RPM was a little high in...- Ray-Ray
