There will not be one size fuse that will work in all situations. Look at a late model fuse block and you will probably see anywhere from a 5A fuse to a 150A or more. Each fuse is designed to offer protection in the particular circuit design and each one has it's own characteristics. If you do some searches you will find fuses that may have the same amperage rating but they will have different operating characteristics.
When designing or adding something like a fuse, circuit breaker, fusible link, and so on, one needs to do the work to figure out the best application. Get it wrong and things will not be protected as they should be.
I think we all would like an "easy answer" to some things but the more specific one is as to what they want to do will give a better design and results. For example, a stock 60's style GM starter may draw let's say 200A on a 8.5 compression motor and a smog cam installed with minimal cranking compression but if this same starter is used on a higher compression motor with a higher cranking compression it will draw more power. If one were then to possibly swap out and use use a gear reduction starter with a lower horsepower motor it might draw more power than a higher horsepower gear reduction starter assembly and then either or both of these could draw more or less power than the standard 60's GM style starter.
