    Iím gearing up for the same swap in my Ď66 Sportvan this fall/winter, especially with the Nats trip in mind for next year. I just swapped a 5.3LS into a Ď36 pickup and I conservatively spent about $2200 for everything (motor/tranny/exhaust/etc) to make the motor swap work.
    Iíll add lots of pics when I start this project.

    Yes it appears I will be doing in my driveway with professional help. The mechanic that had it at his shop for two months lost his lease and bailed on my project. Think positive thoughts for me that the project will go smoothly and completely. Thanks again to M1D for his ground breaking pictures. I am inspired.

    I hope to come in at near your costs on the '36. Did you install everything yourself? What did you pay for wiring and computer flashing? Which tranny did you go with? Any drive shaft work? I could ask 10 more questions but I'll spare you all.

    Exactly what he said. I cut the harness myself, had the computer flashed for $100 from a local guy, my buddy swapped the tail housing on the 4L60e to a 2wd and Iím currently getting the driveshaft made for $250. I did all the work on the Ď36 with a buddy of mine and we spent lots of time online reading about drivetrain angles and pinion angles, fuel systems (we went returnless), and so on and so on. Iíve never done a project this big but the internet guided us well. So now that Iíve done it once, Iím diving into the LS swap on my van this fall.

    Good Ol' Neal tearing 'er down.

    So far we have the following stuff off of the van:
    Engine, transmission, radiator, front and divorced drive shafts, Rear trailer hitch assembly and gas tank.
    There are more hours spent cleaning prepping and painting than there will be installing the LS. The van has surface rust under the floor between the frame rails. I plan to prep and paint with POR15. The trailer hitch is also surface rusted. Man is that assembly built strong. There is a channel frame welded to the rear frame around the fuel tank that supports the trailer hitch front and rear of the gas tank.

    Gas tank has no rust inside so I'll be reusing it. I bought the new gas tank Smiley informed us about I will see if it fits between the rear axle and the transfer case, I believe there used to be an axillary tank there in the past.
