Here's why:
* Different Distributor Heights: The distributor body on a big block Chevy is taller than the distributor body on a small block Chevy. This difference in height means the big block distributor will not properly align with the distributor shaft in the small block engine.
* Different Mounting Points: The mounting points on the distributor base are also different between big block and small block engines. This means the distributor will not securely attach to the small block engine.
Alternatives:
* Small block distributor: The obvious solution is to use a distributor designed for the small block Chevy.
* Conversion kits: Some aftermarket companies offer conversion kits that allow you to use a big block distributor on a small block engine. These kits typically include a modified distributor body and mounting hardware.
It's important to note that using a big block distributor on a small block engine without a proper conversion kit is not recommended as it can lead to incorrect ignition timing and other engine problems.
