62 gmc v6 305 3/4 ton longbed 2wd to 68 chevy k20 4x4 swap

[raylube]

Howdy,i have a 62 gmc 3/4 ton 2wd with the 305 v6 and manual trans and want to convert it to 4wd, it has torsion front and coil rears. I can get a 68 k20 frame and drive train to swap with manualtrans and 327. I was wanting any advise to this swap as i would like to keep the v6. What is the best way to approach this swap both are long beds and so i would assume the wheel base is close. If anybody can give advise that would be great thanks.
