Lifting my 1967 K20

[Chaparralman1974]

Morning all!

So, I am going to move forward with lifting my 1967 K20. I opted for the Skyjacker 4" kit (leaves in the front, blocks in the rear) with the Blackmax shocks. I went with this kit due to the Softride front springs and the good reviews that I have read up on them. It is worth noting that this truck is a pavement princess and will never see any dirt at all! I opted for the blocks for the rear due to my truck being a '67 with the oddball rear leaf springs. The truck rides fine and the springs are not sagging, so I think that a block lift for the rear is the best option. The kit comes with the square Ubolts for the 69-72 trucks, but I will just get a set of "U" bolts built up by my local spring company. I am also swapping out the front axle for a "Big Hub" Dana 44 at the same time so that I can do the power steering / disc brake swap as well.

Obviously, in order to ensure that this truck doesn't look like it skipped leg day at the gym, I am going need to go with new shoes under her as well. I do like my steel wheels (16x8 Ford Accurides). I had them powder coated white and I like the look of them on a blue truck. I am considering going with a 315/75/R16 tire which is 34.6" tall and 12.4" wide. Given my wheel width, should I be worried about backspacing or anything? I definately don't want to trim anything at all but I want to ensure that that the wheel wells are filled such that the truck has a good look to her. Again, this truck is a pavement queen so I am not worried about beating anything up with extreme axle articulation.

I am also staying with the SB327 and 4 speed / T221 combo for now. I did swap out the rear end (HO52) with a 4.10 setup and the new donor front axle is also 4.10's as well. Speed isn't all that much of a concern as I rarely take this thing out on the highway. It is more for pleasure cruising around town. Should I have any concern with this tire size and my gearing? Should I look at a larger tire?
