...It's STOPPING these trucks from freeway speeds that can be a problem, especially since we now are used to disk brake, ABS equipped vehicles.

I'm not sure on gear sets for the 5200lb rear axle, but with the LT 235/85-R16 tires my 283 equipped K20 would roll right along at 60-65. Beware that that Rockwell T-221 Transfer case whines a bit at speed.

I think that were I building a daily driver, I'd at least swap the T221 for a NP-205, is it? T'case. I understand that they are are more highway friendly.

Once again, it's stopping these things in a straight line from freeway speeds.
