lol dat be no datsun/a series head

What "H" number is on that? I've never seen one like that before.

Now don't go spoiling the beauty of a GX by installing that rubbish on the side, stick with the Hitachi's & you will still love it.

The 56A gearbox does not like a lot of torque, which is why it was not used behind the long stroke A14 & A15 engines.

If you are going to stuff a whizz wheel or side suckers on it, then the best bet is probably a 60 series 5 speed from a later model Bakkie as this will help address the short gearing problem that you will have & it's stronger than the 56A gearbox.

@Velociti
Want to ask a BIG something. Can you check if the other 2 has their cylinder heads still on? I am looking for a spare GX cylinder head to modify. If there are 2 I would suggest take one for yourself aswell and throw it on the 1400 and give the other one for me.
If he sells a complete engine for R500 then the cylinder head we can score for cheap.
Please let me know.
Thanks

@ 1200GXman: im going back there later today. I will find out for you about the head and take some pics. I do know that there is a datsun head laying there on a shelf, but I dont know what they are from A12 or A14. Ill get back to you on that one.

Thanks alot.
Throw me a PM when checked.

1200sss was unique to NZ.
Based off the 1200 sedan deluxe.
Its an a12gx, get it

I can GUARANTEE that this is an ideal powerplant for the B20 ute as I used one in my B10 sedan for years & years & ...... well, you get the idea.

If the finished product is to be a toy, not a tool, then replace the differential with one from a 1200. This will remove the 4.375 to 1 ratio, which was OK for a 988 cc engine hauling a half ton, to one of 3.9 to 1 that was used in a heavier vehicle with a lower powered engine [than the GX] & still performed very well. You will need bigger diameter tyres as well otherwise you will make it into fourth within 30 yards & be looking for another gear. LOL

The 1200 is close to being a 'bolt in' but I recomend that you use a 56A series trans from a B210 with it.

There were a couple of minor diferences in the GX distributor, so if you can find the original, or another, then get it. Like the 1000, the 1200 GX used only one spring on the mechanical advance weights while regular 1200's used two & from memory, the weights themselves were different.

The fuel pump also uses a different spring under the diaphragm.

The carbs are not SU's but are Hitachi's They look like SU's, but then a Holley looks like a Rochester doesn't it.

Have a good look around & see if you can find any of the missing parts, including the air filter housing & throttle linkage as they are important & will be difficult to source seperately.

The B20 Ute was the lightest B body Datsun of all, so even a stock 1200 GX will make it fly.

1200 4 door Sedan ....... 1,532 Lbs .... 695 Kg
B21 Ute ...................... 1,356 Lbs .... 615 Kg
You save ........................ 176 Lbs .... 80 Kgs

that manifold is from a A12gx , no doubt.

I think so too,early block,fuel pump,rocker cover all belong together,get the top off and look for the castings on the head.

Looks like it to me, from memory it has NISSAN stamped on top of the head under the rockers, good score if it is!

Just out of curiosity, did you get this with the 1000 ute?
