I just purchased a 1979 210 hatchback with a A14 motor. Are the intake ports round or square. I recently brought two 68 510 ITC race cars and in all the spares is a Cannon side draft manifold with a casting number 836. It looks like a Datsun type mount with the slotted bolt holes for the shared int/exh bolts but it is a square port. Any help figuring out what this fits would be appreciated.

intake ports are either round or oval, and the exhaust ports are square.
havee you got a pic?

the A14s pretty much all came with an oval port head, except the "economy version" which was a round port, but I am under the impression that the "economy" version is not very common.
I guess the only realy way to check is to pull the manifolds off and look. You know for sure that way.

I think we need DD for this one, he would know the answer if it can be answered.

pics mate cmon!

There are no Datsun A-series engines with square intake ports.

We need pictures to identify what it is from.

could it be an atempt at tomie style(I think?) square ports with domed roof? with Im not sure was there own casting or modified round port heads?

what?

I cant find where it was discused but someone put up a pic? I think it was a modified roundport head where they had squared the port (for maximum volume within the boundries of water/oil pocets I guess) and still had a roundish roof..

I think is was 'clyons8' or 'D' ?

Yeah clyons posted pics from somewhere in my thread
