  1. Like I said, this is an old problem. Don't really like the explanation above because it gets too confusing what a valid permutation is.

     

    The easy way to look at this is there are only two possible courses of action: either you switch or you don't switch. If you don't switch, the odds of getting it right are 1 in 3. Can’t change that. That means the remaining 2 out of 3 chance has to fall with the other option: switching doors.

     

    Another way of looking at this is you are being allowed to pick 2 doors and get to throw one of them out after you know what is behind them.

     

    Of course old Monte will trick you up.

     

    BTW, WTF is a "Six Sigma Black Belt"? What does this have to do with Kung Foo anyway? Is this just a Tennessee thing?

  2. That's not a bad idea. The thing I don't like about most rotisseries it the large mounts you need to weld to the front and rear of the car. This would keep the mounts on the underside of the car where it is stronger. With such a design you could also replace front frame rails without worring about the car buckling on you.

     

    One obvious and potentially fatal flaw is it will take more shop space and a couple of strong friends to safely put on it's side.

  3. I hear guys debating for hours about what cam is best for their old school v8' date=' weighing the tradeoffs between smooth idle and top end power, and the tradeoffs between more lift and passing smog, but with the VVT you can just tune the ECU and there will be no tradeoffs.

    No tradeoffs? Are you serious? So there is no reason to ever put an aftermarket cam in a Honda? One could argue whether the average Honda owner is knowledgeable enough to upgrade a cam, let alone know how they work.

     

    The way I see it' date=' Chevy keeping the old SBC design in the vette, and Dodge bringing back the Hemi, etc, is a way to make sales to the die hard fans by retaining their desired nostalgic image.

    You just answered your own question on why the Japanese are so enamored with DOHC. Marketing. Make people think what you have is better.

     

    DOHC, 4 valve per cylinder inline 4 engines have been present in production engines for almost 100 years now. What the hell is high tech about that?

  4. I have read the comments about carbs sludging up the oil before also. The articles I have read claim it is primarily during warm up that the over rich fuel condition causes unburned gas to blow by the cold rings. So over 100K miles is common, but a lot of it has to do with how you drive. Long trips, warm climate (Lambeu Field, baby!) proper maintenance and there won't be as much fuel contamination.

     

    Just makes sense. On the average FI cars will live longer.

  5. ok, so why are manhole covers round??????

     

    Because people have round holes.

     

    The falling in answer is the correct one. I know people who were actually asked that question in a job interview.

     

    Human factor? Ever watched lets make a deal? They don't always open one door and offer the chance to switch doors. Thus there is one more probabilty in your Markov chain. Why are they asking me to choose again? Do they offer this choice more to the guy who has picked right? Or the one who has picked wrong?

  6. We get the little wasps nests all the time. I have a 10' section of PVC pipe I hook up to the vacuum end of my leaf blower. Hold that up to the hole then start banging on the wall with a stick.

     

    Works perfectly. Just make sure you have the bag on to catch the dead bees.

  7. Well, like Dan said, without an overflow tank the radiator will suck in air as it cools. So you can fill it to the top and after on heat up and cool down cycle it will be an inch or so lower. That is how much the water expanded as it heated up. That is why an overflow tank is such a good idea. It keeps the raditor completely full of liquid.

     

    Check the overflow tube coming off the top of the radiator where the cap installs. Make sure that is not blocked, because that is the path air takes coming back into the radiator. It is odd that the system will suck air back in after cooling, but maybe it is only a small amount and not worth worrying about. Are you sure you got the right sized cap?

  8. To expand on what Dan said, you need a new radiator cap. The cap should act as a check valve to allow air back into the radiator as it cools. Just as importantly, it acts as a pressure regulator to keep it at the right pressure. Blowing hoses could mean excess pressure. Buy a new cap every few years.

     

    Antifreeze does more than just keep the water from freezing. It also prevents corrosion of the aluminum parts and most importantly (for a Z) it acts as a lubricant for the water pump. A corroded engine will do more to reduce the effectiveness of the cooling system than water wetter ever could so never run an engine without the proper amount of antifreeze.

     

    Also water expands as it heats up, even if it is well below the boiling temp. Thus once you take the cap off a hot engine, the only way pressure will build back up is if it gets even hotter. With a properly functioning cap the entire cooling system should be completely full of liquid with no air or steam. Steam doesn't transfer heat as well as liquid water. So like Dan says without the pressure from the cap, you run the risk of forming small steam pockets in the hottest parts of the engine. This makes those hot spots even hotter.

  9. They sell replacement splatter sheilds. Buy a few glass ones and keep them handy. Even the most expensive helmet will be ruined if you run it without the shield. Can't blame the tool for that one.

     

    I hear you on being able to see. In my case it is the trifocals rather than the helmet. Try a halogen work light to help illuminate the weld area. And the smoke from the flux core does complicate seeing the weld.

  10. The current bid is only 1800 which isn't too bad. The engine and transmission are hybrid bait anyway so who cares? I have downdraft webers. They are smog leagal and considerably better than the original flat top SU's, but I can say first hand they are not an ideal set up.

     

    The top is really bizzare and like all vinyl has trapped a ton of rust underneath. The paint looks clean but probably covers up many other problems. Dash cap pretty well means no show car. Funny how he tries to describe it as "such a clean original". He appears honest but obviously has an over inflated sense of worth on this car.

  11. Doesn't the LS1 also have a computer ignition? How are you going to back fit a distributor? Guess you could install some type of crank trigger unit, but then you are back to wiring and fabricating some type of bracket for the trigger unit. Doubt you will find many aftermarket intakes and ignition units for an LS1.

     

    How is that the easy way out?

  12. You're honestly considering building a 100 mph go cart with no front brakes?

     

    Another good source of used bike parts is hospital emergency wards. This will have the added benefit of putting you on a first name basis with the emergency room workers. Might come in handy when you lock the rear brakes at 100 MPH.

  13. Brings back memories. Worst class I ever took was a graduate level class in non-linear stochastic processes. I don't know how the professor gave final grades, because with 40-50 grad students the test scores would be uniformly distributed from 7% to 98%. No two people would score within 2% of each other, and you had as many people scoring under 10% as you had scoring over 90%. I have never seen a course like it before or since.

  14. The really early vehicles (like my 12/70) do not have the pocket behind the seat for the retractable mechanism. So whether that pocket is there or not should not be an issue. And like you said, it is not like you can find something that will work in those pockets that isn’t past it’s useful life. Most vehicles with retractable belts have a one piece lap/shoulder belt with the retractor mounted off the shoulder part. So any J/Y solution will not make use of the pockets.

     

    But it sounds like you don’t want a retractable mechanism at all? Sounds like something out of a 70 with the solid belts would be exactly what you want. Might be a tougher find. Also since you had a 5 point in a street car, I assume you realize how unacceptable a solid type belt is for day to day driving.

  15. It is not that big of a deal to install both belts. I have a 70 240 that originally had the non-retractable, separate lap and sholder belts. The PITA with those was the catch part would fall down between the seat and the trans tunnel. I searched a JY and found a set of belts out of a Mazda 808 that had the catch on the end of metal rod. This holds it up over the side of the seat. Mounted the retractable part up on the stock sholder belt bolt. Woks fine for the street.

     

    Interestingly, the stock sholder belt mount does not give you the 5-10 degree downangle mentioned above.

     

    I also have a simpson 5 point harness bolted in. Only used that for auto X. I have it bolted to the shock tower, as did probably 90% of the guys I use to auto X against. Maybe not the best solution, but definitely better than the stock belts alone.

  16. You have no idea what happened in that situation, no idea what the grunts experienced prior to the filming, no idea what their standing orders were and no idea whether they were ordered to destroy the car. Yet some how you feel justified in using terms like "morons" and "trigger happy" and attribute their motives to being "bored".

     

    A couple of words of advice. Don't believe everything you see on the internet and don't try and categorize US service men as a bunch of trigger happy rapist who are out to destroy innocent people's lives.
