If you don't use a flywheel, the engine will not turn the transmission, therefore the car will not move and the engine will just sit and idle and probably roll away because there is nothing to lock the transmission with.
No
You have to use the flywheel for the 1974 engine and the clutch plate for the Trans Am.
A small flywheel needs to stay with the starter that goes to it. You can use either flywheel, and the block should be drilled for either starter.
clutch is used to transfer the power from engine flywheel to gear box
use a wheel puller
Usually it is a flywheel with a clutch to spin up the engine. In some installations they use a small low power electric motor to keep it spinning This allows the backup generator to start producing power in less than a second On some large engine piston/propeller aircraft a small starter engine spins the flywheel and engages to spin the engine once the flywheel is up to speed.
As with any flywheel, bearings are so tight that they are pressed in, you will need to use a puller to remove the bearing from the flywheel in order not to damage it.
Volkswagen designed all its "Upright" engines, which your Bus has, to have the same external dimensions. A 1600cc engine will fit fine, and it's what I would use. You will need to use the flywheel off your old engine because the 1600's flywheel is 20mm larger.
Any Ford vehicle with an identical 8th digit of VIN. The 8th digit is the engine code. However, if you get an engine that was attached to an automatic transmission you can not use the flywheel (you can tell just by looking at them when you have both engines side to side). You can take the flywheel off your current engine and have an automotive machine shop inspect and resurface it or buy a new flywheel. And if the engine you buy has a manual tranny flywheel you should have it inspected and resurfaced anyway (or replace if needed).
yes you can all you need to do is switch the automatic flywheel and putt on a standard flywheel and make sure the clutch from the transmission will bolt up to the flywheel.
remove old engine and install new engine including exhaust and accessory brackets and pulleys. everything should fit. be sure to use a 454 flywheel with 454. smallblock flywheel will work on 396,402,427
No. Chevy uses a number of different noses for their starters. The size of the flywheel and year and model of engine determine what nose is needed. The 153 tooth flywheel is smaller in diamaiater than the 168 tooth flywheel. If you want to use a starter from a 168 tooth flywheel on a 153 tooth flywheel the nose from the smaller flywheel starter will have to be exchanged onto the larger flywheel prior to using it.
