420n620 Posted February 7, 2011 Report Share Posted February 7, 2011 you can also look at the front of the timing chain cover, it will have 2 bolts on each side @ the top instead one. sorry no pic for you. Quote Link to comment
NWOleman Posted February 7, 2011 Author Report Share Posted February 7, 2011 instead of one? does the L16 have just one? oh and it's out of a 76 pickup, just double checked that. Quote Link to comment
420n620 Posted February 7, 2011 Report Share Posted February 7, 2011 here is a L16/18 pic. look just above the water pump you will notice 1 bolt on ea side where the L20 will have (2) one above the other because the L20 is a taller block. Quote Link to comment
