L20b distributor swap

[Ratflame]

Hi, I have an odd combo in my 510. its a Z24 short block with a ported L20B head on it. (seamed like a good idea at the time) I've been using the 1977 L20B point distributor and recently got a 1978 L20B electronic distributor to replace it.

So the electronic one has a slightly shorter drive shaft then the point distributor and my electronic distributor did not come with the extension housing. 

so does anyone know if the electronic distributor had a shorter extension housing, or is there some other difference I'm not seeing?

 

Thanks

All L20B oil pump/distributor drive spindles are the same length.

All L20B timing covers are the same.

All L20B distributor shafts are the same

 

So all L20B distributors must reach in the same distance to the drive spindles. If a '77 worked then a '78 should also.

 

If it does not reach then either it wasn't a '77 L20B or the '78 isn't.

 

My guess is that the distributor you have is for an L16 or L18 engine? Or was modified to reach.

 

There is a part number on the sides of the distributor, beginning 22100-????? If you can post those two distributor numbers we can see what you have and what they are from.

the one out of the 77 is 22100 B8001 and the 78 is 22100 N8502   I don't recall using any of the Original  L16 parts other then the valve cover.

I can send a picture if that helps.
