* Spark Plug Gap: This is the distance between the spark plug electrodes. The recommended gap varies depending on the specific spark plugs used and the engine's tune. You'd need to consult your owner's manual or the spark plug's packaging for the correct gap.
* Point Gap (if equipped): If the car has points ignition (less likely on a '79, but possible), there's a gap between the points that needs to be precisely set. Again, consult the owner's manual for the correct specification.
* Valve Lash/Clearance: This is the space between the valve stem and the rocker arm. Incorrect valve lash can lead to poor engine performance. The correct valve lash varies depending on the engine's specifications; a repair manual specific to the 1979 Camaro 350 is necessary to find the correct values.
* Other Gaps: The term "gap" could also refer to other clearances within the engine or drivetrain, but without more specific context, it's impossible to know what's being asked.
To get the correct information, you must specify what kind of gap you're asking about and consult a 1979 Chevrolet Camaro repair manual specific to the 350 cubic inch engine (small-block or big-block). The manual will provide the exact specifications for all relevant gaps and clearances.
