Hi! I have a chiltons manual for 69 thru 76 american cars... I looked it up and it says that for a OHV 199, 232, 258 it is 1-5-3-6-2-4 in clockwise rotation. Your plugs are numbered from the front as 1-2-3-4-5-6  with 6 being the rear plug.. I have a 72 hornet sportabout wagon with a 232 6 in it.. have fun, Linda

Hello all. I was just recently lucky enough to find a 1975 gremlin in 
my home state of michigan. It is a one owner all original car. It is 
in great shape, but it has been sitting for a long time so it runs 
pretty bad. I am just getting started working on the engine and I 
have not yet got a service manual... can anyone tell me the firing 
order for the 258 inline 6 cylinder???? I would greatly appreciate  
any help.  Thanks alot. Bye
