Realistic estimate Please

If you're talking about the basic swap a weekend would probably be plenty of time. You'll have to get the car way up in the air if you are going to try to put the engine & trans in as a unit. I'd probably put the trans in first & go from there. It's always nice to have somebody there to help, even if it's only to raise & lower the cherry picker while you keep an eye on other things or try to pry things into position.

If you're talking about having a driveable vehicle there are other things to be considered, such as the exhaust system & the cooling system. What manifolds or headers are you planning to use? You'll probably have to cobble something together unless you plan to run stock 273 manifolds. Your /6 radiator probably won't be adequate for the engine but you might be able to nurse it along for a while. The radiator hose fittings on the radiator aren't likely to be in the right place for a 360. If you use a 273 timing cover & early water pump, I think you can then use 273 radiator hoses to hook up to the /6 radiator. I know that on my 64 Barracuda the /6 & V8 radiators had the fittings in the same place. I also think I've read where there might be some minor clearance issues with the 727 in an early A. I'm not sure what mount you'll need for the trans mount but I think the trans crossmember form the 66 will work. I'm sure I've forgotten something but you'll hear from others here.


Looks like C130 Chief covered a lot of the same things while I was typing.
