Re: 5.3 into 1980\'s k10?
that is a heck of a project.
i've never tried something like that myself. but, i know there are some major issues you are going to have to overcome.
i guess you should start at the start. what parts do you have? the 5.3 might not be the best option. i say this because of the LS1. The big edge with the LS1 is aftermarket support. A few different companies have come up with packages to swap those motors into F and X bodies. For you non car people those are camaros and novas. This means stand alone computers and all the parts you need to bolt it into an older car/truck.
as for a trans, you can go with something stock for the LS1 or 5.3. so you have to get the ECM to talk to it. and you are going to need a transfer case if you want 4x4. again, a problem because the stock fuel injected motor has the transfer case output shaft on the wrong side. so, another non stock swap there.
money. another big force in life. this is not something you can do with just junk yard parts. this will require a good deal of cash. look at spending a bunch on the resto, and maybe 5 grand extra for the modern motor.
just some thoughts.
lifts are easy. cross over steering, 4 new leaf springs and shocks. it will ride fine. Good search cross over steering to learn more.
