Lockleaf Posted March 6, 2015 Report Share Posted March 6, 2015 This engine is for sale near me and I just want to know which engine it is before I decide to go get it. The owner claims it's a 1976 but didn't know which engine it was. It is attached to a 4 speed trans that supposedly came with it. Thoughts? http://www.ksl.com/index.php?page=1&ssid=33702931&nid=389&rnid=218#1 Quote Link to comment
DanielC Posted March 6, 2015 Report Share Posted March 6, 2015 It looks like a L-engine to me. Quote Link to comment
Lockleaf Posted March 6, 2015 Author Report Share Posted March 6, 2015 That's what I would think, I just am slightly weirded out by the fact that the serial plate looks more like a J than an L to me. But having never owned an L, or a J, I wanted a more experienced eye to look at it for me. Quote Link to comment
datsunfreak Posted March 6, 2015 Report Share Posted March 6, 2015 That's what I would think, I just am slightly weirded out by the fact that the serial plate looks more like a J than an L. Definitely L18. J18 is a smaller pushrod engine, and has the distributor on the other side. Quote Link to comment
Lockleaf Posted March 6, 2015 Author Report Share Posted March 6, 2015 Ok cool. That is two of you who would know better than me who say L. I think I'm going to buy another engine. :-) thanks guys. Quote Link to comment

Ask someone who has a J series exactly where the engine number is located on the block. The L is directly behind the dip stick.. Quote Link to comment
datsunfreak Posted March 6, 2015 Report Share Posted March 6, 2015 There were no '76 L18s in North America, one year only '74. Probably an import motor, as would the J18 be (only sold in Mexico AFAIK?). I've bought a lot of various Datsuns from the 70s that had L18s transplanted. It was sold in other markets for many, many years, so there used to be a glut of "low mileage" L18s from engine importers. Quote Link to comment
Lockleaf Posted March 6, 2015 Author Report Share Posted March 6, 2015 Hmm interesting info. Cool Quote Link to comment
wayno Posted March 6, 2015 Report Share Posted March 6, 2015 I would say it's an L block because of the exhaust manifold and where the dist. is, all the J blocks I have seen had the dist. on the right side. Quote Link to comment
ppeters914 Posted March 6, 2015 Report Share Posted March 6, 2015 (edited) What john and wayno said plus that trans. It's an L18. Edited March 7, 2015 by ppeters914 Quote Link to comment

datzenmike Posted March 7, 2015 Report Share Posted March 7, 2015 This is a 71B transmission, a four speed. The 71B was never made to fit a J series engine. By the looks of it this is a '74 620 engine and trans. Quote Link to comment
Lockleaf Posted March 9, 2015 Author Report Share Posted March 9, 2015 Thanks fellas. I'm now the proud owner of an L18 and a trans. It even came with the front half of the drive shaft. Nothing to put it in, but for the price I paid, I can't go wrong :-). Thanks for the help. It's bolted to a welded steel structure and rigged with an ignition coil so I can even run the engine as it sits if I feel like it. Kinda neat Quote Link to comment
wayno Posted March 9, 2015 Report Share Posted March 9, 2015 What is the head cast designation? Quote Link to comment
Lockleaf Posted March 9, 2015 Author Report Share Posted March 9, 2015 It's an A87 head. Quote Link to comment
wayno Posted March 9, 2015 Report Share Posted March 9, 2015 I have something like the engine stand, but I put wheels and a bracket to put a radiator on it, it was made for a diesel engine though, no coils or anything like that. An A87 head is a good head, it might even be a great head depending on the valves, and if it is a closed chamber. Quote Link to comment
Lockleaf Posted March 9, 2015 Author Report Share Posted March 9, 2015 It will probably be a long while before I open up this engine, so I won't know if it's the closed chamber version or not. That engine run stand you built is great. I feel like it should have a motorcycle solo seat mounted on the narrow part of the trans and maybe some handle bars. Make a bitchin ratsun trike!
