You can play around with tire diameter, rpm, gear set.
You will want to find out what RPM your 250 will want to cruise at (2000 rpm perhaps?) with the most torque.

Thanks for that site.
33.5 inch tire (My rears are recapped 8R-19.5's right now)
4.10 gears
60 MPH
Yields an engine RPM of 2,467.
250 seems to want to be at around 1,800 to 2,000 for peak torque, so might be twisting a little hard to maintain 60, but I'll probably go the 4.10 route and see where we are for a while.
Haven't driven a 6 in a while so I don't remember what RPM's they seem happy at for long periods. In the long run I might do the headers and the 390 cfm 4 bbl carb, but not right away.
Any trailer I'd pull with 3,000 lbs. would have brakes. Also, whether I stick with the HO72 or go with the 14 bolt, Disc brakes are planned on the front and probably the rear too.
Thanks,
