I want to be able to reach high way speeds in this truck. I was think a t-5 transmission out of a 1985 older s-10 with a macchnical speedo but what kind a rearend that would match with a 3.3:1 gear ratio.

Though it will need spring perch work...which is minor in my opinion.
If you don't care about keeping six lugs in the rear, there are many 5 lug car rear options. | | | | | Joined: Dec 2004 Posts: 1,897 Shop Shark | | Shop Shark Joined: Dec 2004 Posts: 1,897 | The way I see it, you only have 2 choices... 4.11 stock or 3.55 aftermarket. Swapping out transmissions and moving to an open driveline will give you more options. You are pretty much limited by the torque tube. | | | | | Joined: Mar 2004 Posts: 874 'Bolter | | 'Bolter Joined: Mar 2004 Posts: 874 | If you have the truck 4 speed (SM420) you can easily convert to open driveline by swapping out the rear bearing retainer and u-joint from a later model. Trucks 1 ton and heavier from '48 up also have open drivelines. | | | | | Joined: Feb 2009 Posts: 14 New Guy | | New Guy Joined: Feb 2009 Posts: 14 | Ok I can see this is going to be a problem to meet my speed goals and keep original three or four spped tranny. I want to go highway speeds of today so what rear end and manual transmission do you recommend thta will adapt with my 235 ci engine to meet these goals | | |
