Guess who was right.... Bad crank angle sensor... They even said they want to get an oem one because anything aftermarket sucks.... Should have it back today....

Hello fellow enthusiasts, been a lurker for a while and I can proudly say I have joined the fold last week with a purchase of a 74' 620! I haven't done a complete run through of her since I've been buryed with snow but I do know she's a 5 speed L18. She came with plenty of work already done however she far from where I want her. Here's a list of my goals with this project and what I'll be picking yalls brains about! She's going to be part time cruiser/ part time drifter. I've put a few things sideways but now I finally have my project. Ball joint conversion Rear-end strengthening Coilovers/or bags? Roll cage Efi while I save for a decent swap, Making her look pretty Pictures to come, as always thanks!

You're welcome. Hope he can send it. Randy's a good guy.

You have definitely done this truck justice. Beautiful!!!

Welds are ehhh.... but they’re strong. I could have got after it with a grinder, but they just fucking seat mounts. Besides these pics, no one will see them. got the other seatbelt out of the 69 dime. Started mounting it in the this car. Same procedure, through the floor, seal, bolt down. still hunting for more appropriate vinyl. I’ll check locally. Not holding my breath.. I don’t really want the inner rockers to look like an extension of the seats.

got the interior vinyl sample but it’s not like the factory pattern. It’s better than what I got on amazon, but a smaller print for sure. got the drivers side seat brackets finished and painted. I had to modify one bracket to add an anchor to the factory seatbelt mount since I relocated the mount to the seat.

If you’re planning on drifting it, you’ll want to go coils. How good are you with a welder? The only 620 drifter I’m familiar with was Chad’s. It was covered by Motor Mavens. To my knowledge most of this is custom work. https://motormavens.com/center-stage-datsun-620-warmachine-pickup-sr20de/

Puking out radiator fluid came first, then I discovered moisture on a spark plug. For some reason water never turned up on the dipstick. As long as your head/block aren't warped or cracked I'd stick with your J engine. Parts are easy to get. Pulling the head off is not too big of a project and you can just replace your headgasket while you're in there. There's even a good video on youtube about adjusting the valves on a J engine. I did mine recently and it was maybe a 5 hour project. And I work slow.

I did. I got the K667 kit, which comes with the manifold for a 620, plus the linkage. So, I guess I didn’t get the 521 specific manifold. My guess is that the runners on the 521 manifold are much smaller in diameter on the head side, since all 521’s ran the 210 heads with tiny ports. The manifold I got (MT-0037-C) does have a picture. It’s a 2-piece unit, and the guy on the phone went and grabbed one and measured it for me. It’s exactly 38mm (1.5”) which is the same as the ports on my head.

Did you get the intake from them too? I have always entertained the idea of adding a 2nd weber but I've done so much work to make my single work.. I ask because i saw a 521 specific manifold for dual 40s being offered as well as a couple others which I never saw available before.... of course no pictures on the website of the one I wanted to see.... I'm just glad to see more new things available for these old trucks....

If that falls through, I'll get my hands on the one down here. Actually I totally forgot, there was one in the wrecking yard local to me. Just now thought about it. 😐 So lets say, there are at least 2 down here.

I need to copy this. I have so many things ran above the engine and one less will be that much nicer 😄

My Clutch Master we getting pretty bad - so I decided to replace the Clutch master and slave cylinders. Well, the non stock 7" booster makes it really hard. I found the factory 4" booster on RockAuto about a year ago and never installed it, so now looked like a good time ... because I had to! Before: New 4" booster and new clutch cylinder with my 15/16" Also - - - -I ordered the conversion kit from Beebani so I can upgrade to the larger rotors and Z32 4 piston front brakes for my D21 spindles. Should be here a a few weeks, so I'll update that as well when the time comes. I dont recall seeing one on a 620? .

Soon to be retired. So now all I do is work at thinking things up.

Why ford 9 inch specifically? That is a massive axle. Seems like it will introduce a ton of unnecessary load by being overkill. Ford 8.8, even though the ring gear is only a little smaller, is a much smaller axle, and very easy to narrow, and has disc brakes and LSD options. Have you considered Rodeo/Passport dana 44? Disc brakes, buildable to handle any power that KAE is likely to make, plenty of LSD options, relatively narrow, and it does offer the stock lug pattern. Or wagoneer dana 44 if you want to stay drum?

In middle of summer, it feels like a desert. Lol

I know. That's the joke. 😁

Nice bum.

hopefully going to get to my truck sooner than later. earlier last week I stopped by and retorqued the head, got a decent turn on each bolt, so hopefully the headgasket stops leaking oil. the carb had a vacuum leak between the top hat and main body, could see on the gasket where it wasn't crushed when I took it apart. I used some Permatex fuel resistant sealant with the gasket, should work well. also had a massive vacuum leak at the base of the carb, and again can see were the gasket between the bottom of the carb and spacer did not seal on one side. going to use the sealant again and then test for vac leak, hopefully that fixes the wicked high idle and overheating issues. also need to adjust valves, and put the original fuel pump back on to see if the seal works. I will update once I have a good verdict on the seal. hopefully it works, I cannot stand the look of that garbage Carter pump.

That would make sense....

I searched radiator hoses, good call on heater hoses.duh

Iv got a gen 2 mono with some gen 3 guts more or less lol some former contractor gear

Not at all, only that the compression is pushing the water out past the rad cap. If there is water in your oil, most likely the head gasket is blown into the water jacket. Some coolant is bound to get in the cylinder and work it's way down past the piston and into the oil pan.

Very much doubt they got anything wrong, reported exactly how they intended it to be reported.

Well, there’s $1100 worth of Pierce Manifold goodness showing up in about a week. I called them up and they custom jetted a pair of DCOE 40’s how I wanted them. Great people to work with.

How does your booster get vacuum? NVM, I see you ran it under. Very clever

You're doing it wrong, it's gonna be at least tomorrow before dude rebuilding his 4x4 620 gets another video up. He's probably recording another song

Eh. I'm too busy watching someone rebuild their 620 4X4. Can only youtubes so much!

Rad!

Lol ..Only sweeping i want to do is when this project is done 😆

Sweep the leg, johnny

Just watched his whole series on the series twice..i laughed i cried i learned enough to be dangerous..im ready for the match..i feel confident coach..hope i dont forget something and end up having to use the crane stance 😉

Oh sweet good to know hes around ratsun seems like a dope dude.

BTW he goes by Hainz or Banzai510 around here 🙂

Btw this master has not a drop of oil sparing in a white GI proves his black belt ..while the untrained similar to cobra kai wear black which says shows lack of discipline 🇯🇵

Is this a flowery way of saying you are going to need help to change your timing chain, grasshopper??????????

Got one set of brackets done and painted. since the receiver is mounted to the seat, and the factory seat mount is spot welded to basically nothing I added a mount to the factory seatbelt mount location. Will it hold in a wreck.. maybe? It’s 1/8” steel. Would the factory mount hold, absolutely not. Finished the seatbelt receiver mount. Tossed the seat back in and gave the seatbelt a try and happy to report they work fantastic and they are not in the way.

Got the seatbelt hardware from planet seatbelts.

Received the carpet today. Test fit one piece and my initial thoughts are they are nice and fit one the one piece is good. Quality seems good. I’ll be ordering some floor mats to cover the floor mats..

I read on another website that this cover works for the 620. Here is a quote from a user on the datsunmimitruckin site, "this is an Extang rail system tonneau cover off a hardbody. dimensions are perfect on the rails and the cover for a datsun bed. the only mod i did was to bend the clamps slightly to clamp on the inside of the datsun bed. u also have the option to add hinges and a couple strongarms so that the cover can lift open from the rear." I assume this is what he is referring to: https://www.autoanything.com/tonneau-covers/60A1074A0A0.aspx (sorry for the photofucket )

Found a place to take some photos

Recent pics over the weekend

Looks good. I also had to fab a throttle cable bracket on my 74.

EI coil came in. Now to install

EI match box Hooked up. using points coil for now. Used wire from another wire harness to keep it stockish looking And it looks like I still need to re link my pictures
