Stovebolt Posted February 24 Report Share Posted February 24 Hello, glad to be here. So, I have had this truck for over 20 years and it is time to rebuild the motor. Its been a ranch truck . Never did anything to it other than spark plugs 1 time and made a new gasket for the glass plate carb when it started leaking. yep never changed the oil or filter. or anything. Don't Judge me it was an experiment. It still rips, but is starting to smokes a little. It is now time to rebuildt and give it some love. I feel it deserves it.I know it is a not the original motor that was in it. there is a bunch of "smog stuff pinched all over the manifold and block. so here is what i know the block says on passanger side 7111B N56 the head says A87 it has a Hitachi Carb. What is it. The valve cover ribbed says Nissan OHV and the oil filler cap has "S" on it. For those who want to know about the truck the door plate says 10/69 and the plate in engine compartment had engine # of 355302 and a car #218945. Thanks. Quote Link to comment
datzenmike Posted February 24 Report Share Posted February 24 11/69 production makes it a 1970 model year replacing the previous J13 engine with the L16 or 1.6 liter engine. If it hasn't beed swapped. Look on the boss just below the head on the top of the block just behind the oil dip stick. The engine displacement is stamped there. The A87 head was primarily used on the L18 but it will fit all years of the later L20B too. Quote Link to comment

Stovebolt Posted February 24 Author Report Share Posted February 24 Great never saw that it says L18 21478 Thank you very much. Knew I came to the right place Quote Link to comment
datzenmike Posted February 24 Report Share Posted February 24 The L18 was used one year only in the '73 610 car and one year only in the '74 710 car and 620 truck. Not a lot around. Quote Link to comment
Stovebolt Posted February 24 Author Report Share Posted February 24 That was my next question what year when looking for parts Quote Link to comment
datzenmike Posted February 24 Report Share Posted February 24 The L series are the same for rebuilding, all L18s are the same. Oil pans will be different for different applications and carburetors similar but different in their emissions requirements. Car alternators are larger than truck alternators but this is all bolt on stuff. Quote Link to comment
Stoffregen Motorsports Posted February 24 Report Share Posted February 24 Bring it by the shop. I can help you ID it and figure out why it's smoking. Quote Link to comment
