Quote:100% correct.
When sorting out such a car it's best to restore the engine & its equipment to original working order. This can involve replacement of a lot of vacuum hoses & some service work on some smog gear, but once it's all done you have a reliable reference baseline to work from.

As long as compression is within factory specs & everything else is doing what it should, you will be surprised just how peppy it can be, particularly with the A15 engine.


Here's a breakdown of the plate code.
H= 1400cc engine
L= Left drive
B= Small Datsun model
3= Fourth model in this small car series [B10, B110, B210, B310]
10= Passenger model [the suffix 20 would designate a commercial model of Datsun]

Trans
F= Floor shift
S= [Ummmm, I forget]
5= five speed
W= wide ratio, this is the standard trans version
60= Basic trans model. It actually refers to some internal dimensions & the bigger the number the bigger/stronger/heavier the trans. 60 is just right for these cars
A= Improved model

Final drive [differential] These cars used the H150 model which breaks down as
H= Hitachi. This was the sub contract supplier of differentials for Datsun.
150= The diameter of the ring gear in Milimetres


The plate code breaks down as
H= Hitachi.
B= second, or revised version [the previous version was HA]
37= 3.7 to 1 diff ratio


Sorry about all the edits but this version of the forum sucks
Bring back the old forum.
