Yes it has the same bolt pattern and starter location.

The same basic transmission was in use throughout the Datsun Nissan timeline FW71 is the base # A was the early 5-speed, B is the mid era and C is in use up to the Frontier. The bolt pattern changed when Nissan went from the L20 to the NapZ engine family and the KA has the same pattern.

Weight? Is that Texan for wait?

 

The 720 transmission weighs about 70 pounds. 

 

The Z series and the KA series engines sit at the same angle and the mounting bolt patterns for the transmissions are the same. So yes, the 71B 4 or 5 speed from a 720 will bolt to a KA24E or DE. You should be aware that the 71C transmission from a KA engine is about twice as strong as the earlier 720 71B transmission. The KA engine is about 50% more powerful so a 71C is the better choice

Update 4-19-19 in all honesty if you can get an s13 setup its better than an s14. S14 head has a part in the cast that blocks the throttl cable. Its a pain in the ass but easy to fix.


I was able to track down a s14 set up for a reasonable price. What is the fix for the throttle cable issue ?

So ive got alot of revizing to do. Even show how to wire the alt. But i veen working alot.

But 

I learned somehow i mixed up parts and the water pump pulley is to be left alone. And the single cam pulley is somehow bigger byva cunt hair. Trust me i removed it a buncha times and the belt would work with one but bot the other.

Anyone try this with a 1968 520? If so what issues/differences did you run into? 

 

Yes, it has been done a few times. 

Does this have a J series engine?
If so the main difference is the the stock engine mounts at the frame will not work, they need to be cut off. 
I have weld on frame side mounts that replicate the 620 frame mounts which make the rest of the swap the same as the later trucks.

Awesome! Looks like I’ve got the L16 in it right now but the data plate says J series. Do you sell mounts for both? 


If the truck has the stock Lseries frame configuration you would not need the weld on frame side mounts. You would just need my engine side mounts. 

It really depends on how they swapped the L16 in there. Do you have pictures?

I’ve got a ‘69 521 with a J13. Do you know if these fit that frame? I’m not sure if the ‘68 520 and ‘69 521 frames are the same or not. Thanks Pidge.

They are the same other than the engine mounts which is why I developed the frame side mounts.
They should also work in a 320, but I have not verified if the frame width is the same on those..

Thanks. I’m on the fence. I didn’t know you made KA mounts for the early 521 w/j13. Looking around online, those motors aren’t cheap anymore. Thanks again for responding to my question. I have some thinking to do. 👍👍👍

I do know that the 320 frame is narrower than a 720 frame. From when I swapped a 720 balljoiint suspension onto my 320. It was a few inches difference.
