620 KC in Texas


Recommended Posts

Well, thanks to Bob3 I am the owner of a new to me 1978 King Cab 620 Pickup Truck. This is my second Datsun (in recent years), but this one has the Ratsun feel and I am going to keep it that way.






It's almost legal in Texas. Passed inspection.




Now all I need to do is get the Texas DMV paperwork done and I'm on the road.


Merry Christmas to all.

Got a little work done before Christmas and still working on the Truck. I purchased a 60 Amp alternator for a 720 to upgrade the 35 amp stock unit and purchase rod eyes and an adjusting bar from McMaster Carr to fab up a new adjusting bar. The new bar makes it really easy to adjust the tension on the alternator.

I had to get a longer V-belt since the alternator is slightly larger and was hitting the water inlet to the block.

Also, I have a new Weber 32/36 installed and running. I just got a JAW Wideband connected and will be tuning the Weber with the wideband. I'll let you know how close the stock Weber tuning is for this L20B.

I have a question from all you 620 guys.


I hooked up the vacuum port to the brake booster and it seems to work, but I have never driven a Datsun with power brakes and an wondering how the peddle should feel. I have driven it without the booster connected and it stopped well, just took a little peddle effort, but about the same as my non-boosted 510. The peddle seemed a little mushy once I connected the booster. Is this normal or not?
