  1. My guess is the spark plug area opens up the mixture area around the plug for more reliable ignition. The troughs in the intake likely route any liquid gas droplets to the best side of the intake to hopefully prevent wetting/fouling the plug, probably for starting issues - and possibly reintroduce the fuel into the airstream at the best point for breaking up droplets? That side of the port probably flows more air. What do you think?
  2. Bump- Mike what do those oe plug wires look like?
  3. More info? Turns out I was not able to get the Z20 trans. Thanks for the good info. Does the info apply to a F5w71a/b/c transmission also? or is the early bell housing not compatible? something too different?
  4. And might want to make sure non of the backing plates are bent while you are in there- that all shoes sit on a flat parallel surface? So the shoes are "straight" and the friction material is not at and angle compared to the inner drum. A matter of good eyeballing or using a bar w/ protractor?
  5. Not sure if my post got in. Another thing to check! Check the countersunk screws that hold the drums to the axle flange and front hubs. I use a little grease or antisieze and torque tight so the drums have no movement. I use a "hammer on it" hand held impact when I do mine to get tight without damaging the phillips. It drives the force down into the phillips as you torque. My sisters honda was clunking in the front brakes- turns out the locating screws on the rotor were not tight, It clunked even with the lugnuts torqued to proper spec. Replacing the damaged countersunk screws and torquing them fixed it. Apparently the brakes/trans applied enough rotational force to be able to move the rotor when going from fwd to reverse at high idel and sometimes braking.
  6. Check the drum surface, Might need cleaning up good if they got brake fluid or crud on the inner surface. I would check the shoes to see if they fit the drum inner circumference correctly. They may need arcing. Also the front shoes are directional so make sure both are in correctly. I normally do't turn them, just clean super good with something like purple power. Then sand the braking surface evenly all around the inner surface with paper between approx 100 grit and 220. you want clean metal with no black staining, I just sand them back and forth in the same direction they turn. Check for a inner or outer ridge on the inner drum wear surface, might need turning the minimum at a good shop to remove if there is a ridge so they don't grab. Put together and bleed brakes good all around. Than adjust up so cant turn by hand, then back off a couple clicks. Then get inside and hit brakes good a couple times to help center them. Than retighten bit by bit till cant turn by hand. Back off until you can barely turn them and repeat process. Rarely are the drums warped enough to be a problem, if they are really out of round you will need to turn or new ones. But not likely. Once you are satisfied they they have been cycled and centered a couple times tighten a click or two until they drag just enough you cant turn by hand. Hit brakes again and check. might need to go a click or two more? Or if dragging back off until you hear/feel them barely just rub in one or two spots as you rotate the wheel. Not scraping or locking up- just barely touching both sides. Do it by feel so both sides are equal. I am in Fountain Valley. You can hit me up if needed. Scott
  7. Can you post what Ratsun stickers and items you have for sale? Current update?

      I have rising sun stickers, hoodies and t-shirts. 

  8. What are the angles on a 411sss and roadster intake? And is the bowl on one "slanted"? If the carb is at an angle it it ok or change the mixture?
  9. I have been looking around to see if a z20 5 speed will fit a l series application. If I have a stock L series 4 speed is there a front housing that could be swapped between the two? Ending up with a Z20 4 speed and a L 5 speed?
  10. Any idea what jack a pl-310 or a 312 came with? and where stored?
  11. do you still have the air cleaner and guages? Scott In so ca 92708
  12. Thanks. I think my 4 speed is earlier than 71 series so I will have to check it out. Thanks for the good info.
  13. Reactivate! Will a L series 4 speed front case work on a 5 speed?
