    Things ALWAYS take longer than we think. Just having all the required tools often takes one time through the job. I'd figure at least a few days if you have a fair amount of experience.

    Edit: the 22" radiator is probably just fine.

      2 Hours to pull a drive train swap out a big block and get it running with all wiring, fluids, driveshaft, hood installed and exhaust connected?
      Not for me, I'd plan on a week.
      If I had every single thing I needed maybe 3 full days.

        The K member is the same, need the BB motor mounts. If the SB had a 727, I think the trans X member and trans mount is the same. Not sure about the driveshaft.

          I was kidding! :D If you had all the parts, and help... maybe an all nighter.

            The main takeaway is......
            There is no cutting, welding, fabrication necessary........ provided you have all the correct parts on hand.

            In my 68 Satellite I’ve had a couple of different 440’s, a 340, a 400, and a 383.

              And for clarification , this is a R/T convertable. It has a 318, so i dont know if its a real R/T

              An R/T should have a 440 so likely not, it would be surprising for someone to go from a 440 to a 318.

              The VIN should clear up if it was an actual R/T or not.

                Not mentioned above is the exhaust. Have a plan. Nothing worse than finishing everything else and having to keep the ride short because you’ve got open headers.

                Doh!
                Still will need more than just hooking up exhaust

                  That's a project for someone REALLY experienced and sure will require a ton of other mods to the car.

                    2 hours...until you get to the bolt that you can only turn 1/32 of a rotation at a time without repositioning the wrench and it takes you 1.5 hours to remove. Then you will snap another bolt and it will take 6 hours to get that out. Add in 4 trips to the auto parts store to get some obscure tool or part you never thought you would need. At least another hour spent cleaning oil/trans fluid/coolant off the garage floor that spilled. There are endless time-sucks that turn every 2 hour job into a 3 day journey. It has almost become a joke in my house when my wife asks how long it will take to do something. She will triple the time I tell her. Unfortunately, she is usually right.

                      If he is really talking a 440 to Hemi conversion, figure on 6 months at least maybe a lot more.

                      I don't think there's that much time in the stage 5 conversion is there? That has pretty much bolt on from what I understand and maybe have to have bosses welded on the block otherwise it's a standard build. We're going to use six pack rods and that kind of stuff but he's not looking for a 600 horsepower Street motor he wants more to look.

                      Go for it. I bet the Hemi heads will give you trouble.
