This isnt a build thread and its for a later model chevy but alot of you here seem to have 4x4's so i thought i would ask for your opinions.that being said here goes.

ok my dad has 73 2wd 3/4 ton which has been sitting for the last 5 years.i would like to buy it from him and turn it into a K-20.truck originally came with a 454 and TH400 and if i recall its a cheyenne super so its pretty well loaded well as loaded as you'll get for 73 anyway.truck currently has no motor or trans.my plans are to add a front axle,4 inches of lift,33 or 35 inch tires,unsure on the motor but ill add a 700r4 for better driveability,not sure which tcase to use and the rest will be determined later.so my questions are what would be a good gm front axle to use,which would be the best tcase behind an auto trans,what other situations will i come across in turning a C-20into a K-20.

The problems you are going to run into is you will basically need everything off a 4x4 frame to convert to a 4x2. If you do have the donor 4x4 frame you can swap the body over easier.

agreed, swapping the body will be easier, if only slightly.
