The P510/PL510 Datsun is a very nice classic car with its own rich racing heritage which I admire a lot. Together with the 70's classic lines and quad headlamps it seems to grow on you every time you look at it. Together with the endless types of nissan engine conversion, you will be able to built monster at ease that are able to take on much modern sport cars easily. I chance upon this Japanese site which contains lots of information and pictures of 510's in it's natural glory.
Sorry its in japanese language only but you can drool at their photos gallery which contains endless supplies of immaculate condition 510. This classic ride will definitely be in my wishful list.
The Nissan P510/PL510 was sold from 68-73 in many variants throughout the world.
The 510's engineering was inspired by contemporary European sedans, particularly the 1966 BMW 1600 incorporating an SOHC engine, Macpherson Strut suspension in front and independent, semi-trailing arms in back. The European-influenced sheet metal design is attributed to a young Datsun in-house designer, Teruo Uchino. The engine was pushed through by Nissan USA president Yutaka Katayama, a design developed through Prince, an acquisition, with some Mercedes Benz influence.

The Datsun 510 released to the U.S. market came originally with the Hitachi downdraft carbureted 1.6 L L-series engine, with an advertised gross power of 96 hp (72 kW), front disc brakes, 4-wheel independent suspension (MacPherson strut front and semi trailing arm rear- wagons had a solid rear live axle and leaf springs in back), rear wheel drive, and either a 4-speed manual or a 3-speed automatic transmission. 2-door sedan, 4-door sedan, and 4-door station wagon variants were available. It achieved 20-30 mpg in factory trim (U.S.). Non-US spec models were also available in a 2-door coupe body style with the "SSS" packages, which included a 1.6 or an uprated 1.8 L L-Series engine and dual Hitachi sidedraft carburetors, which were a copy of the earlier British Skinner's Union (SU) design used on Jaguars and MGs. SSS models also had numerous other small changes like sports instrument cluster, tinted windows, different interior trim and of course 'SSS' emblems on the rear qtr vents and grille.
