Took this from another thread
I'm getting this info from my dirrect connection performance book
426 hemi num 341841 19.50 overall 10 inch housing
440-6 num 341841 21.35 overal 11.75 housing
440 4 3769123 22.85 overall 13.25 housing
thanks for that!
interesting, as I looked at those, I would think the 6 pack cable would be the longer one. both the center 2 bbl and the 4 bbl sit in the middle of the manifold, but the primaries of the 4 bbl would sit farther back toward the firewall, as from front to back it is a longer dimension than the 2bbl.
anyway, I'll try and look those up.
