    AFAIK and remember it has run well before. This is my Dads' baby and I am just trying to catch up on what has been done or changed. I was hoping for a smokin' gun/easy fix, but I will take suggestions from these guys and dig into it. Starting with the grounds and working my way through it. This is a great community of learned people!

    That set up was suggested by our Feng Shui coach. We have fired him. Our trials have been run without any air cleaners on.

    I just did a quick look at 8V batteries. Most of them seem to be deep cycle for golf carts. The automotive units I have seen seem to cost about the same as an Optima 6 volt, but have less CCA (in some cases, significantly less). I am aware that total power is rated in watts, so amperage can be about 20% less and still be equivalent, but that doesn't seem to be common . The deal breaker with me is the increased voltage, which requires asking the voltage regulator to do something it wasn't designed for. And no matter what anybody says, the 33% increased voltage has to be hard on the light bulbs. At my age, blowing one under dash bulb would not be worth any advantage any 8 volt battery could possibly have.

    Sorry, but with 6 volt Optima's available, I would strongly advise against an 8 Volt battery. Your time would be better spent chasing down the poor connections and eliminating the voltage drops requiring one rather than stressing your regulator to get it to do something it was never designed for. Do they make 8 volt regulators? I have no idea, but I'll bet they are very expensive if they do.

    Thanks for that. What's the advantage of using an Optima battery? I don't know much about them. Cheers, Dave

    Although they are still lead/acid batteries, they use a new technology called Absorbed Glass Mat that does away with the liquid electrolyte. Instead, the electrolyte is contained in the internal structure of the battery. I am not an expert, so I don't know exactly how it works, but I can tell you it works well. As I see it, it provides three benefits. First, the battery can be run in many positions (e.g. on it's side). Second, somehow they produce more power than a typical "flooded" battery. They have 800 CCA (Cold Cranking Amps), vs 550 or 600 in a typical flooded battery. Third, they last a long time. I'm on my third Optima in my '51 since the mid-nineties, which means each has gone 12-13 years before needing to be replaced. While they are quite expensive (>$200.00), life that long actually makes them cheaper than a regular battery in the long run.

    What are the drawbacks? Well, they're kinda weird looking and quite frankly, ugly. That can all be remedied by buying a special case and top that effectively disguises them to look just like a vintage battery.

    Wow what a NICE coupe.

    Start there, it may just be struggling to breathe. And its a FREE, QUICK and SIMPLE change. My favourite type lol.

    FYI, it doesn't hurt the voltage regulator to crank the voltage up two volts, easy to adjust too. I do prefer 6 volts over the 8 volts though, mainly because you don't have to buy an 8 volt charger or a special battery. You just have to have good wiring and connections for 6 volts.

    The best advice I can give for your situation......

    If the car is indeed for sale, leave it alone, sell it as is.

    Mission creep is real.

    You are correct; I have had several expensive cases of the "Might as well"'s.

    Anyway, people like 'em better untouched.

    Thanks. I gotta ask; what is 'mission creep'?

    It is for sale. I'm going to invest some time and minimal dollars with some of the suggestions I've got from here. And then, ya, I'll do the as is thing. It's a beautiful car, someone will take it on

    You find a minor problem, and decide to fix it. In the process, you come across something else that really needs some attention so you decide that you "might as well" straighten that out as well. In three weeks, the car is in pieces, spread all over the garage., with no prospect of running and driving in the immediate future.

    It can also get expensive when you decide to upgrade parts (sadly, like a Mallory "flattop":().

    Leave it for the next guy. People like "untouched" cars that they can add their personal touch.

    Your car appears to be exceptionally nice, so it may be the exception to the rule.

    Reminds me of a '61 Chev stepside truck that a little old lady in my church asked me about that her great grandson wanted to sell and he didn't have a clue about. It had some serious nice work done by some previous owner. I told them to leave well enough alone and sell it as is. Often wonder what became of that truck. I should have bought it.

    Wow, that was quick !
    But it is a beautiful car and not excessive price.
    Hopefully a Hamber following this thread bought it and we will get to see more photos of it ?
