moparvwfreak Posted July 23, 2012 Report Share Posted July 23, 2012 under teh #3 cylinder there is an ID boss. it will say either L16, L18 or L20b. Quote Link to comment
DAT510 Posted July 23, 2012 Report Share Posted July 23, 2012 If for some reason you can't find the Id plate.. There is a Casting rib behind the dipstick on the L20B, I think the L18s have that too. L16 Quote Link to comment
datzenmike Posted July 23, 2012 Report Share Posted July 23, 2012 W-58 heads wouldn't work properly on an L16/18 and were used on the '78 and up L20Bs. Block ID is just behind the dipstick handle. From the front there are two pair of top timing cover bolts on an L20B. L16/18 only have one per side. Quote Link to comment
