It depends on your skill level, what engine you are replacing with what engine, what vehicle you are removing from and putting in, tools, and how much time you have. Is it EFI or carb? Are you going from carb to EFI? Carb to EFI? It can take a day or it can take a year lol.
It can be done over a weekend for someone that's done an engine swap before.
at least 10 hrs
2 hours to 7 hours, depends on the engine size.
it should take about 4 and a half
Petrol engines 4.8 to 5.0 hours dependant on cc of engine Diesel engine 7.1 hours.
That depends on the boat, and on the engine. If it's an outboard engine, it takes about 2 minutes. If it's built in, then it could take hours, or perhaps days. Or longer, if the bolts have gotten rusty.
Take the engine completely apart, because it's located between the two halves of the engine case.
easy, take out the old engine, and put in the 350. it really is that simple.
14-18
forget the chey and buy a new ford
depends on your mechanical prowess. if you've never done a swap before and you haven't done a lot of research on what it takes and what to expect, then its probably going to take you awhile. I've done it a few times with my hatch and it only takes me a few hours to get the old engine out. from running to sitting on ground outside the car. AllData quotes approximately 8.5 to 9 hours. depends on whether you have a/c or p/s still intact.
5 hours
