I am sort of worried about running 4:57 gears were we live (I-40 Texas) people are all zipping by you at 75-80 mph. I was thinking about 4:10 or 3:73 gears but wasn't sure if I could find a donor vehicle, any ideas? I heard from a buddy who said 3/4 ton up to '72 ring and pinion would interchange. I am running a Straight 6 (216, I know what your thinking this guy is an idiot well the last guy who owned it was the idiot for putting a 216 in it) and dont want to run that fast maybe 60-65 so i dont need anything flashy. Something to keep from getting ran over. Thanks
