i'm sure had you fallen in love with it you'd find a way to fit an o/d trans and/or more freeway friendly gears to the axle. at least there wouldn't be any trans tunnel mods to do, lol.
neil.
ps i've adapted a late ford 4r70w o/d trans to the '63 fe big block for my '58 rambler american i'm building as a gasser. at 2200rpm it'll be right around 75mph. that's with the explorer's 3.73 gears and 295 50 15's so it'll be lively off the line too.
