Gentlemen;
A stock 1958 235" engine only requires 10KV to start & run properly in ANY climare. The factory (GM) gave it 15-18KV when it was new. This allowed for slow cranking/low battery voltage and 'push starting' with It's generator (only).
This can be raised to 20KV (twice that required) by adding an 'extra duty' coil.
Raising it beyond that is 'NUTS'.
These (precision made) 50KV distributors are for high compression/V-8 engines in extreme (high RPM) conditions/racing/commercial usage.
His 58 Chevy (engine) will be turning between 2,100 & 3,000 RPM @ 60 MPH depending on which transmission GM put in. That's 1,050-1,500 (disrtibutor) speed.
Keep this up & he'll think we don't know this "over here".......
