early hemi distributors

Are the distributors in the early hemis all the same length?
from the low deck 331 and 354 to the high deck 392's.
Thanks for any info on this issue.

392 has a longer shaft,as the block is higher.

 

What he said... also, there is some more info on early Hemi ignition at the link in my signature. Check it out. Maybe you'll finding something useful.

Cheers!
