Datsun L-28 long block (N42/N42) - A Very Desirable Block and Head Combination

Featured Replies

For sale is one L-28 long block. This is the desirable N42/N42 block and head combination.

About 10 years ago, when I needed to build a new engine for my "track day" car, I located and purchased three of these N42/N42 engine and block combinations. The first block we sonic tested accommodated my requirement of an 89 mm bore size, so I didn't need to use either of the remaining two spare engines. These remaining two were removed about 10 years ago from cars which were in the same salvage yard in VA and have been stored inside my garage since. Both engines rotate by hand. I now need to free up some space in my garage, so I am interested in selling one of these off.

Long block option #1: Price: $750 $650 plus shipping to your location or you can pick it up in Marietta, GA.

As you can see, option number one is pretty clean with no corrosion on the cam/valve train and has a clutch pp, disc, and flywheel.

Long block option #2: Price: $500 $425 plus shipping to your location or you can pick it up in Marietta, GA.

As you can see, option #2 shows some wear on the cam lobes which also have rusted.
