DWELL

[COSTICH_ALAN/HPATC1_01@i3125ent.atl.hp.com]

So, I came across this old dwell meter. Cleaned it up and
got it to work.

Now, I have this '74 BGT (GHD5) with an engine/motor of
18V672ZL. My Haynes says the dwell should be 60+-3 on
one page and on another page it says 51+-5. The book also
says plugs should be gapped to .24/.26...on one page and
on another page .35. No where does the book list an 18V672ZL
engine/motor.

So, who has the correct specs?
