Hey guys just working on my 90 bronco 2. Just trying to decide on 4.88 or 4.56. I've got a 90 ford 302 efi i'm dropping in with a m5r2 and np271. Axles are 8.8 rear with hp dana 44 front. The axles were in a diesel conversion ranger that was parted out and they had 3.73 ratio so either way i'm swapping gears. I'm stuck between the 2 ratios but thinking 4.88s might be a better choice as my 302 will basically be stock. intended use is weekend wheeling, some summer daily driving. Not a dedicated trail rig, might even use it for hunting so i'd like it to pull the quad too.
I live in Canada so our speeds are slower than most of you USA guys. And with all the mountain passes in BC we need all the help we can get getting up hills. Limits are usually 62 mph and sometimes 68( say 60-70 for a nice even number). But, having driven my ranger on 35s and sas and good size lift(i robbed the suspension and axles for this build) 60 mph is a handful in the corners as is, lol.
pheww, sorry this is a bit long winded, haha. Last point. People say 302 likes 2100-2500 rpm cruising and 4.56 would put me at 2200 at 62 mph and 4.88 would be 2400 rpm at 62 mph.
What are your guys thoughts? People who have 4x4 v8 conversions i'd love to hear what you guys did. Thanks!!
