Best wheel size for 4" drop
 

Just finished installing 4" drop springs in the rear of my stepside 68. Right now it has the original 465 4 speed and 4:11 posi gears. I've decided to ditch the 6 banger and go either small block or ls swap, depending on what I can afford. Regarding wheels, what would be the optimum tire/wheel size with a 4" drop that would help me not turn too many rpms at highway speeds, and not rub or stick out past the fenders? I would like them tucked in nice and tight. I also know someone with a set of 3:08 gears that I can get, so that may be an option also.

Your gonna want the tallest tire you can fit without rubbing, but there really is no way around the 4:11s being a screaming highway gear with a 4 speed. The 3:08s would be the better for highway use, but its gonna not be real fun with a stick in town.

I'm getting ready to see with my '68, and pretty stoked about my upcoming drop. The rear is at 2", and is dropping another 3" - the front will be 4" Using the corvette style rallye wheels - 7" in front, and 8" in back (15's) Front tire 235/70/15 and rear 275/60/15. Had the rearend rebuilt a year or so ago and stayed with new 3:08 gears and added an Eaton POSI. Really love how it runs.
