yes
If it's still factory it will have an HEI ignition system.
No points after 1974.

yes the 1974 caprice classic came with a 350 small block
8 degrees
The dwell for the points should be 30 degrees. The spark plug gap should be .040".
400 small block 2brl was the basic engine with a 454 big block optional
General Motors stopped using points distributors in 1974 when they began transitioning to electronic ignition systems. This shift aimed to improve reliability and efficiency in their vehicles' ignition systems. By the late 1970s, most GM vehicles had fully adopted electronic ignition technology, phasing out the traditional points system.
According to the info I have these cars were available with four different engines. The 351 Windsor/Cleveland the 400 Cleveland (all small block) and the 460 engine (big block). Hope this helps.
As far as I can tell , yes ( in 1974 , depending on size of engine , there were either points or electronic ignition )
The make and model would help because Ford, Chevy and Mopar made small blocks.
The point gap on a 1974 Yamaha DT125 is typically set to 0.3 mm (0.012 inches) when checking or adjusting the ignition points. This gap is crucial for proper ignition timing and engine performance. It's important to ensure the points are clean and functioning correctly to maintain optimal spark and engine efficiency. Always refer to the service manual for specific instructions and tolerances.
