Re: tuning the A series

Its important to remember when watching the video that he is talking about the A series mini. Datsun A series heads are a completely different ball game. Luckily nearly everything he talks about doing to a mini head comes stock on almost all A series heads , ( especially the later ones). With regards to droplet sizes , Datsun heads can take a far more atomised ( smaller fuel droplet) fuel air mix due to many factors not least of which is cooler running temperatures and better port design. Pay close attention to your valve size, shape, lift at early opening intervals (Cam profile) and seat design. Datsun heads (a series) respond brilliantly to correctly installed efi.
