These were found in a hoard of Roadster, 510, Z car and other L series Datsun parts.

 

An L-4 or maybe a Z series cranshaft, but which one...L16, L18, L20B, Z22, Z24 ?

 

Dual SU manifold which appears to have the bolt pattern for Roadster 1600/R16 carburetors

 

Anyone in Ratsunville have a guess?

The dual SU manifold is for/will fit a L16/18/20b.

Do you mean L-series four banger? L4 is a generic term for any inline four cylinder engine. http://en.m.wikipedia.org/wiki/Inline-four

Its not an L20b crankshaft

06W is HL720. Z22 crank?

Thanks for the replies...it still doesn't clarify much, but it's more than I knew before. I was referring to a Datsun L-series four cylinder engine when I used that term ("L4"), to distinguish it from an R, U, A, J, CA or Z series motor. I didn't bother to open the Wikipedia link, but I thought "I-four" or "inline 4" was the generic way of denoting a four cylinder--to me, L4 has always meant an L-series Datsun 4 cylinder overhead cam motor which first appeared in the Datsun 510, as it's called in the US market.

I know the manifold will fit an "L4" cylinder head, but I just wanted to know is it meant for 1600 Roadster SUs, or those smaller flattop SU carbs I've seen here & there on other Datsuns running non-US spec carburetion?

My fault for taking a picture of the crank casting upside down, I thought it was M90, not O6W. If I'm correct, a Z22 crank will work in an L20B block?

K14 manifold has larger ports, compared to the more common 220 intake

I have 46mm SUs on my K14

 

 

 

................................Z22 block also has 06W stamped on it......................
