I've been leaning toward the 4:88s and back to the 5:29s. I'm torn on them. The 5:29 is the gear set for a good price. The 4:88 is the whole 3rd member for a lot more. I haven't been able to find a definite answer on what the power is in this truck but I know it has a ton of torque compared to its up.

Thank you guys for all the info. Tires I'm planning on 295/75R22.5 low profile or a very similar size. Since I have an HEI distributor and plan to swap the carb shifting her that high shouldn't be a problem. It's going to take some driving around empty to figure out what makes her happy. I have a handful of things to do to her before I put a plate on it and drive it down the road though.

As dumb as I may sound I've been on YouTube a lot looking at videos of guys driving down the road in these old trucks, looking at their engines/trans/rear ends and I'm fairly confident with the opinions I've gathered that I should be best off with the 4:88s as a happy medium. I plan to have this truck for a very long time so if I happen to over gear it I'll just have to add more power to it. Weather it be an engine swap or something else creative. I've come across an 8.1L vortec complete with harness, all sensors and an automatic transmission for $1800 (I wouldn't use the trans).

Buckshot... that sounds like it was a good time cruising all over the place! I can't wait until mine is all set and ready to go! I'll probably get me a new saddle tank this week if I get time so I can go further then 50 miles on a tank.
