Can anyone help me with this question?

What are the specifications of the J15 engine that came on the datsun 620 and in the 521.

The engine looks like the A15, but witch is the better?

the a14 camshaft fits the J15?

The J15 can be upgraded?



thanks

the j 15 is one big hunk of a motor
it has iron head and looks at least twice as heavy as the a series
i have one in a fairlady 1500 and it aint inspiring
the a series is a far better motor in my opinion as it at least has decent valve stem seals and a head made of a 20th century metal
ports on the j series arent too bad but not good enough to justify the weight

oh did i mention the cost and scarcity of parts for the j series??

dont even get me started!!

ben

ops nvm sry, read the post wrong

The J15 is a very good engine.
The A15 is a GREAT engine.

so, the engine is not the best to do one upgrade to a datsun 1200?

thanks to all

I can get my hands on a wreak of a ute with a j15 in it if any 1 wants 1

I'd like to know if a J15 crank fits into a A14/15 block!

seriously they are a bigger motor!!
either i am thinking of another J series or they are deceptive cos they look as big as an L series

I think the J15 has a three bearing crank.
