Olds engines
I have two olds engines.One is a olds 403 and is not working.The other is a olds 307 and works but throws white smoke.Can I swap parts from the 403 to the 307 to fix the problem and to add power to it?

Seriously, it depends. Both motors are small block Olds motors, so much is common, however as noted above, your smoke problems likely require repair to parts that are unique to the 307. It also matters whether the smoke is wispy white (water) or heavy bluish white (oil).

Welcome to the site. Are you sure its smoke and not steam. Does excess water drip from the tailpipe when the engine is running. Have you checked to see if the water in your radiator is low. Could be a blown head gasket
