to remove distributer from old engine, remove distributer cap, noting the position of rotar button. remove one bolt that secures distributor to block. lift ditributer out paying attention to the movement of rotor button. u need to note this when re installing so as distributor goes back in, close to same timing setting. replace bolt but do not tighten fully you will then need to recheck timing. if timing is correct engine will start. if backfiing occurs, your distributor is in , 180 degrees wrong. remove distributer, turn rotor 180 degrees then reinstall. check timing again

How do you install the pickup in a 1990 ford distributor?

Typical: Remove distributor. Use punch to tap roll pin from gear at base of distributor. Use an arbor press (not a hammer) to press distributor mainshaft out of gear. Shaft will then easily come free of the distributor. If a hammer is used, now replace the complete distributor. Unbolt the pickup and replace. Reinstall shaft and gear being sure that gear hole aligns with shaft hole. Install a new roll pin. Install in vehicle. Set ignition timing.

How do you install a carburetor on a 1990 Chevrolet one ton with a 454 engine?

Since a 1990 truck has fuel injection, this will be a difficult and expensive task. Everything one the top of the engine will need to be replaced. If it has a throttle body instead of individual injectors the intake manifold, distributor and wiring will all have to be replaced. You will need to decide on what distributor will be used. My suggestion is to come up with another plan unless you have plenty of time and money.
