8x19.5 wheels and tires (stock option, hard to find!)
Custom made 20" dually wheels with 7.50x20 tires. I made my own out of 50's chevy truck split rims with 10 lug pattern on same circle as the 61-68 6 lug 300's, torched out the center hole to fit. Have hit 103 mph with the 4.88 rear gear in the W300.
The 5 speed trannies from that vintage are almost all direct drive 1:1 in 5th.
As mentioned I want to keep the power curve so I would lose that with tall wheels. I agree that the old five speeds are 1 to 1.
I was thinking about later model five speeds that are behind that same "bellhousing "bolt up" to tranny." Thanks a bunch for your viewpoint.
