  1. Believed to be.... either it is or it isn't.

    L16 to L20 swap

    All L16 had 'number heads'. The 210 head is rumored to have been designed for the L14 originally. On a 2.2 is has to move over 37% more air.

    L16 to L20 swap

    The '82 720 will be a Z22 or may have a transplanted Z24 but either way a Z series engine. Clean smooth reliable but not barn burners. Faster and more powerful than an L16 but you will need a Z series transmission. There were 26" long 5 speeds for a Z series, if you can find one. It will match your 26" 4 speed so the drive shaft doesn't need to be shortened. Easiest fit is a complete L20B with flywheel and clutch and put your engine brackets and oil pan on it. As close to 'drop in' as there is and fits your 4 speed.. Your exhaust manifold will also fit. Depending on the L20B year you may have to use your intake. Good so 'see' you Cleary.
  4. Generally as the years go by brakes tend to get better and larger. I have a set of '74 and '76 710 front brakes and they interchange but the '76s are larger pads and calipers. I'm guessing the B210 brakes will not be an improvement over the 210s.
  5. Try... https://ratsun.net/classifieds/category/9-datsun-parts/ I had one probably from a Roadster. I used it on my 710 so they are out there and will probably work on the SSS
  6. I don't recall any manifold vacuum used on the old chokes. Exhaust is under pressure and will find it's own way to the choke. Chrysler has the coil mounted in a well in the exhaust manifold with a linkage up to the choke flap. Datsun cars after the Fairlady were semi-monocoque or unibody construction. Trucks had frames.
  7. Your 'deep state" is a conspiracy theory.... https://en.wikipedia.org/wiki/Deep_state_in_the_United_States Conspiracy theory..... https://en.wikipedia.org/wiki/Conspiracy_theory Conspiracy theories resist falsification and are reinforced by circular reasoning: both evidence against the conspiracy and an absence of evidence for it are re-interpreted as evidence of its truth,[5][6] whereby the conspiracy becomes a matter of faith rather than something that can be proved or disproved (i.e. the conspiracy is pseudo-scientific - it fails to comply with the scientific method).[7][8] Research suggests that conspiracist ideation—belief in conspiracy theories—can be psychologically harmful or pathological[9][10] and that it is correlated with psychological projection, paranoia and Machiavellianism.[11] Psychologists attribute finding a conspiracy where there is none to a mental illness called illusory pattern perception.[12][13] Conspiracy theories once limited to fringe audiences have become commonplace in mass media, emerging as a cultural phenomenon of the late 20th and early 21st centuries.[14][15][16][17]
  8. Stroke determines red line. Well piston speed actually. Pistons move faster on a longer stroke engine at the same RPMs. They have to travel father in the same time. You want a piston speed of no more than 4,000 feet per minute on stock rods and pistons. Imagine an L20B crankshaft rolling on the pavement while you are driving along at 89.8 MPH. That's how fast it would be spinning. More than 4,000 FPM and the rods and rod bolts risk stretching from the tremendous g forces decelerating and compression on accelerations. Piston rings can flutter up and down in the ring lands. L20B and Z20 86mm stroke 7,000 Z22 92mm stroke 6,650 Z24 96mm stroke 6,350
  9. My 521 did so did my new '76 B-210. My '78 620 did and my 710. I'd say they all do. This is why they all say LEAN<<<<< >>>> RICH on them.
  10. It's also the coolant recovery. Any coolant expelled after a hot shutdown will siphon back into the rad when it cools down keeping it topped up. Use a 50/50 anti freeze mix and fill to the line on it. Check when cold. If it's going down then there is a possible leak or the head gasket. A properly working cooling system with the coolant recovery reservoir will not require any top ups.
  11. I heard trump had a minor day surgery to have Graham's lips removed from his ass.
  12. They will interchange. Are they the same?.... doubtful. Why???
  13. The heating element only turns the choke off at a set rate. You could speed it up or slow it down but why bother? Many of the later 720 carbs the choke adjustment is gone and the choke cover riveted on to prevent owners from meddling with the factory setting. Adjust twice a year.
  14. Oil Today's oils are lower in the anti scuff ingredient ZDDP by about half. Our engines were designed when ZDDP levels were around 1,200 PPM and today's oils are around 600PPM so it makes sense to find an oil that has the original amount. I use a diesel oil made by Shell called Rotella T4 as diesel engines are still flat tappet. Look up the ZDDP controversy and make your decision before your next oil change. Head gasket The Z24 is notorious for blowing head gaskets every 100K. White could be steam from coolant. If you are constantly topping up the rad this could be why. They also tend to not run well with a bad gasket. Not saying it the gasket, but could be. Fuel filter Always a good idea. Change every 3 years.
