  1. Here are some of the goodies I've aquired since this project started. Waiting for the right moment to add on. Not exactly as shown but leaving this option till last. Have another idea before this one. All of these items I bought separately but have fit them together for a visual. Not sure about the throttle linkage set up?Mock up in reverse. Will match port prior to permanent installation.
  2. Thanks for the suggestion. Funny thing, while I was walking the pouches in the back roads, I came across what looks like reminisce of an engine under armour rock plate, just lying there, so I picked it up and used it to cover the hole in the floor board. Custom fit over the floor board hole, drilled several small holes through both metals and glued in between to seal, then riveted altogether. Quite solid, but finished off by coating the under side of the floor pan with weather resistant spray in a can.
  3. Had to check out your threads full topic, amazing dedication and persistence, especially with what's going on all the time in your life. Relentless and inspiring! You also have a wonderful group of friends, amazingly strong connections, KUDOS! Thanks for some inspiring ideas and possible leads. Unfortunately I don't have such a great selection of used parts to pick from. Spend most of my time searching and scour the internet on both sides of the border for that right replacement part. But in the end, it all pays off, right? Good luck on your 520 build, looking fantastic by the way. Rat-a-at-Dat
  4. Dismantled all of the components on the cylinder head, flushed and cleaned. Removed the exhaust internal liners. Started head work. Simple preliminary grind work, nothing too fancy, yet. A rough first cut to get rid of the carbon build up and smooth out the lines. A before shot. Will attempt to remove material up to the darkened ridge outline ( used a felt pen to scribe the inside of the overplayed gasket ) A glimpse of the runners for cylinder numbers 2 & 3 after opening them up. If I ran a felt pen line down the inside of the runners, I could maintain just the right amount of material removed (Exhaust hole). Watch out for the head bolt tube on the left. Intake flute. Used a finer cutting bit to hog a smoother surface. Oops, this one is out of order. Should have been #1. My bad! Nearing the final stages, not too shabby! Pulled the engine to start the rebirthing of this truck. Installed the refreshed head. Time to shine, yeah!
  5. Once an assessment had been taken and the overall dynamics of the condition, a plan was set in motion. List everything according to priorities; type of repairs, parts availability and free time to facilitate repairs. In the mean time; source, accumulate, accrue and amass particular components for all projects. Note: this is NOT my daily driver. Up until recently, its primary function was to enjoy the summers and drive in a classic vehicle. First objective, repair rust in passenger floor board, strip out cab and dash, repair all electrical issues. Just a small hole to patch on passenger side, found it when the aging carpet was lifted. Cause is from a leaky heater core. Dash removal; electrical and a/c piping issue, plus ignition tumbler keeps locking up. Floor repair plus an additional kick panel with speaker replacement next. Yes, the a/c does work, for a 4 cylinder. Double rainbow with my truck at the end of it! Lottery ticket time?
  6. In this shot the windshield had just been replaced, the tires and rims were all selected and hand picked at the nearby 'Pick&Pull' scrapyard. Rims came off a Pathfinder. As you can discern, the front bumper has many distinquishable protrusions caused by the PO navigating his oversized Winnebago around a sharp turn while forgetting about the vehicle tagging behind him, thus the bumpers met cabeza a cabeza! A closer observation on the paint job reveals degradation throughout, but still a solid body.
  7. I really like this colour and have incorporated a similar shade into my engine build. The exact colour mix name is 'Smuf Blue' and I've limited the usage area to the exhaust manifold. Strange yes but with my conceptual ideas, this is part and parcel of the project. Fingers crossed.
  8. Great idea, I’ll shelf this knowledge for future reference. However, I may have mislead you and others indirectly. You see, some of these pictures and notes have all been previously done ( to a point). I’m merely negotiating my privious obstacles and enlightening (hopefully) the readers of this particular post.
  9. I've mentioned earlier of a head gasket repair, just to initialize its ability to travel and carry passengers, namely me. No pics however on the windshield replacement or the very unfortunate occurrance of the new windshields crisis, unless of course you can identify the results in a few certain pics. This pic illustrates the engine prior to a head gasket replacement. The air filter canister top cover had overspray from the splash job that had been done earlier in its life. Head and accessories pulled off together The flip side, with all the anti air polution control crap. Sorry about the pic, camera was having a drink earlier. Notice the issue with the water port in the upper right corner!? And the headless block w/o a timing chain support, oh my! Needless to say, some encounters are prone to give us wisdom. Learn by your mistakes! Timing chain stretched, identified and catalogued. A future plan is formulating!
  10. Little bit of knowledge goes along way... thanks Atomic. The truck was purchased after several months of pursuing the owner through his son at work. I'd seen it parked behind a Quonset on the son's average one day and decided to inquire. His father had purchased it in Arizona to drive around in when they visited there. He even installed a hitch adaptation to pull it behind his Winnebago, thus trailering it behind, too and fro Alberta, for many years. Then the traveling subsided, the truck started having mechanical issues and was parked, until many years afterward when I noticed it. Short story longer, I aquired the truck, without any Datsun experience or knowledge. It just happened to speak to me, I guess. The condition was remarkable for the year and thus the begining of my saga. Engine bay after the head gasket was replaced. Different angle, driver's side. Right side angle.
  11. A good day to all my fellow Ratsunites! Finally, with determination and a little luck, I'll definitely share with you some pictures of my 1979 720KC and hopefully through its transition periods. But first, I shall ramble and bore you with new buyers consequence. I was under the impression this truck was indeed a 1980's built vehicle, but when the dash panel had been detached for clock issues, it was apparently the beginning of a long and drawn out adventure. I began to notice several subtle things were not perceivably acute to the indicated year on the Bill of Sale. In fact, many nomenclatures related to Datsun and/or Nissan kept me wondering about its background. Two things were immediately obvious, the s/n on the dash ID plate didn't correspond to the door pillar plate. Other differences had been identified when the interior work had started. Supporting evidence, and detailed accountability through research has resurrected the mysterious and illusive origins of my automobile. Nonetheless, my desire to modify this ( older ) new found project shall begin.... https://postimg.cc/tsjY6Zbg https://postimg.cc/dDhkccnJ https://postimg.cc/sM414jf4 https://postimg.cc/LhGqHQ0L
  12. I'm thinking of incorporating a heat shield on my build. It's an L20B, and now has a Cannon intake with dual Webers. Just resourcing a smaller diameter b/booster for better fitment, air filter clearance is the issue here. Any ideas regarding which heat shield to use with said configuration?

      Make your own out of sheet aluminum or header wrap the exhaust manifold.

      I don't believe anyone actually makes a heat shield for dual side drafts. I have made them in the past and they serve two functions: A - to isolate the carbs from the high heat of the exhaust just below. And B - to tie the carbs together when using a centerpull linkage (to avoid the single twisting linkage to cause them to go out of synch.)


      A - you can build it to isolate just the heat at the front of the carb opening or you can build it to curl under the carbs to keep the underside of the float chambers from getting hot.


      B - if you are using soft mounts between the carbs and intake (which I highly recommend) and a centerpull linkage, you will need to tie the carbs together somehow. The frontal heat shield kills two birds with one stone.


      I do have a template that was designed by Datsun Comp back in the day, and I have used it to build many heat shields, but it does not fit all manifold configurations. And there are no mounting provisions on most intakes, so mounting the shield gets tricky. Back then, they simply used springs wrapped around the intake runners to tie it to the intake. We also sandwiched a sheet of asbestos cloth in between two sheets to help further isolate the carbs from the heat. That worked really well.


      Hope this helps. Good luck.

      techno toy tuning makes one 

      i believe it mounts between manifold and carbs but dont remember for sure 

  13. Quite impressive dedication and enthusiasm! Kudos to your relentless and ambitious progress too! 

  14. Additionally, without complicating matters, an alternative brake booster has been found! A 1972-1974 Datsun B210 has reared its magnificent and prolific engineering properties, which illustrates the brake boosters dimensions are equivalent to the 610's but the mounting studs attached to the rear of the booster are longer than its successor. The pedestal is a visually solid structure with internally bored channels for these longer studs that extend through the fire wall and mount from the inside the cab ( an over sized spacer? ). Conversely, adequate modification is required but regardless, a notable and doable alternative. It appears that FrankRizzo's comment states the 535311's are 'out of stock', so this substitute is found on RockAut, p/n: 535300.

    Require, in 'good used' working order, a 5 1/2" diameter diaphragm brake booster assembly from early seventies 610 pickup trucks, approx. '73 - '75. Please contact me if you have or know of someone who's interested in parting with said item. Thank you very much.
