Default GM HEI Distributor Difference ??

Just wondering if there is any difference between the big block and small block GM HEI distributors.

If there is, can someone please explain the difference.

thanks

The single point and TI distributors will interchange, so it's reasonable to assume that HEIs will, too.

ALL Chevy V8 distributors are interchangeable. On a mechanical distributor, the centrifugal and vacuum advances may not be appropriate, and the drive gears can change based on the camshaft material. But they fit.

RACE ON!!!

[Qualification] On standard, passenger car, deck height blocks.

348 and 409 distributors will not fit small blocks or later model big blocks

I didn't forget the "W" engines when I made that statement, but I ASSUMED, since all others were interchangeable, that those were, too. I stand corrected, and thank you. I've learned something.
