long time admirer of 620s wanting to dive in

Recommended Posts

Hello, I've always wanted a 620 since i've seen my friend's 720 back in the early 2000s. I finally feel like I should get one, but have very little experience in building cars.

 

My plan is to buy a nicely working 620, and just maintain from there. I've been lurking the forums for a bit and haven't really found much info as to how to get started or what things to look for. I did read that it's a great starter project and fairly easy to maintain.

 

I don't plan on going too crazy with mods.

 

If any of you fine folks can point me in the right direction, I'd greatly appreciate it.

 

Also, I'm in the northern los angeles area, and if there is anybody willing to show me the ropes, that'd be even more awesome!

 

Thanks!

Try to get the most complete example of the 620 you dream of. Even if you have to save up and wait for it. Buying one that doesn't run and needs work is very disappointing. I would suggest a '78 or '79 as these had ball joint steering, disc brakes, internally regulated alternators and electronic ignition. Being in California be sure it has and will pass any future smog testing before buying it. May vehicles are missing equipment that has to be found and replaced.

Before you throw $$ away, and get in over your head, take some basic auto repair classes at a local vocational school.

Start amassing tools, as nothing screws up a car as much as trying to work on something without having the correct tools to work with.

Also get a FSM or Factory Service Manual for the year you buy. Try e bay or amazon. It will pay for itself the first time you use it.

Here's ya some reading material to get acquainted with the little 620's internal workings. This is 77 manual so some of the stuff that Mike mentioned that are features of the last couple years are not included.

I acquired our one owner '78 Longbed (believed to be 150K miles and it has all the good stuff that mike listed and 5-speed trany)  five years ago with a bent valve. Replaced the valves and all the small ancillaries on the engine and it is pure sex to drive around town. Kinda like darting around in your favorite pair of britches.

 

That L-Series engine is an amazing little machine.

As a fellow Californian, my advice would be to get a non smog year and learn as you go. There’s really nothing very complex about a Datsun, fixing is usually easy. I do agree with getting the nicest possible example you can.

Just buy a broken one with good body, way more fun that way. :-)

 

But I guess my definition of fun isn't the same as some other peoples.

If a smog required vehicle, remember, in California the seller has to provide the required smog test certificate.  Don't pass up on this by law requirement!

I would not buy anything that requires a smog test in California or anywhere else for that matter.

Yes, a pre '74 will not require a smog check but you don't get as much either. Smaller engine, lots of dodgy mods to the engines because there are no emissions testings to worry about, a poorer transmission, king pins, poorer distributor etc.... and not to mention they are an older model. A later '78/'79 that has passed smog (also more valuable because of this) will continue to pass smog in the future with little effort on your part because it will be complete.

..and I would never buy anything that has king pins in it.

wow. you guys have responded with a lot of info! this is all amazing.

 

I'm definitely looking at anything with l20b since those seem to come with 5-speed MT. I'm definitely going to make sure it's going to pass smog!

 

Anybody in the LA area want to show me their truck and talk "shop"? I'll buy you lunch! Or beer. whatever floats your boat!

 

Otherwise, I'm going to continue to do more research and see if there are any White l20b 620s out there with minimum rust and lots of love from the previous owner.

 

Hey @datzenmike, any reason why 78/79 are the years you keep mentioning? Also, I read somewhere that the early 70s and late 70s have slightly different bodies/?

Front disk brakes and ball joints. Optional king cab too.

I can get rid of kingpin front ends, but I cannot get rid of smog laws.

The 5 speed was only an option on the '77-'79 620 truck, they won't all have it.

The previous model truck the PL521 '70-'72 was much different looking than the 620. It ended production in early '72 or just over half way into the '72 model year.

 

The 620 was built from around April '72 through July '79. In model years this would be '73-'79. There were no '72 620s as such, and half year models move into the next year. All 620s looked the same body wise. Hoods fenders doors all swapped. All reg cabs were the same and king cabs were the same as were long boxes and short boxes. Minor things like the gas tank was moved to and mounted on the '78-'79 frame rather than the underside of the box, radio antenna on the left side on the '79.... things like that.
