    SCOOTER--- I had my motor rebuilt and dropped ALOT of money in my SBC in my 72 C-10. We made the mistake of running the old msd that was in it and it did not give me the power i payed for. My dad had a Hunt Mag layin around from the previous years' sprint car. We threw that in and it woke that friggin motor UP! I couldnt believe it. I would definately run one if i could afford it in my 331. If they have a refurbished one, see if they have another one for me! Id love to get another one!

    Ok how about this for an ignition system quandry. I am putting together a blown 392. I was looking at running a MSD, but at the Torco show a couple weeks ago, I met someone who told me you could get a Joe Hunt mag w/ electronic internals. So you have th eold school look, but todays electronics. It looks like Hot Heads carrys them also, but for me there is a problem, there is a $200.00 difference between the mag and the MSD. Soooo is it worth it for the nostalgic look?

    Mike
    hoping to get more ideas next week in paso

    Hello..I was at his shop Friday..He's 15 mins from me..I went in to see about a look alike mag..It's an HEI..drop in and go..$645.00..It sure would look good in my 241 Red Ram..I think a real Mag. is to much for the street..He has a web site..Google Joe Hunt..
    I'm close to him, if you need any help let me know..

    I was looking a few months ago and heard whispers about quality issues with the HEI based hunt units. Suprising since the HEI is a durable piece itself. Anyway, my combo involves the hot heads oil pump shaft and a mid 70s LA smallblock electronic unit with vacuum advance. To avoid the clutter of the stock mopar box, purchased an adapter to put an HEI module on the bottom of the distributor. It's all tucked so deep in the engine, pretty much invisible. Since the mopars all used small caps, should have a stock look with modern reliablity. Actually pretty cheap as a side benefit, the rebuilt distributor was like $30. Good Luck

    I have a friend that had a Hunt HEI Magneto in his SBC, and he had nothing but trouble with it. I believe it uses HEI technology, but nothing inside can be swapped with a regular HEI. The modules kept going out on him. Went through 4 modules on two different units. Sent it back to Hunt, got it back, and still the same story. If you blow a module on a Hunt, you'll be parked until they can ship you a new one from the factory. No off the shelf parts inside. He finally gave up on them and put a stock points dist back in when it died in the middle of Oklahoma on a road trip. I personally don't trust them.

    Great info here! That's interesting about the problems Hemi-roid's friend had. Anyone else have this experience? Thinking very seriously about getting one of these HEI/Mag-looking dist., but if they're going to be problems then screw it, I'll go with a regular dist.

    We run this 5.7 Amp vertex modified with external condenser and coil with the big cap and rare earth magnets by Spud Miller at Fuel injection enterprises. If you need a mag or one worked on get ahold of Spud, he is the best. [​IMG]

    In my 52 Chrysler Hemi I'm running BubbaGMC's set up. Simple LA dizzy with an intermediate shaft from Hot Heads along with a GM Hei module mounted on a large aluminum heat sink. I also added a .7 coil from Summit to work with the HEI module. Works great and relatively cheap compared to other set-ups.

    That Cirello rocks Lippy, but isn't BBM distributor rotation counter clockwise? The early Hemi's are clockwise.

    I would LOVE to get a Cirello Frankenstein to run on the digger but I just can't afford it.

    Choke...Cough...wipe coffee off screen...Yikes...I should take mine out of the garage and put it in a safe until I get the motor built :eek: Anyone know where to get a rotor for one of these? Mine needs one.

  17. Well...my Stock dual point DeSoto distributor converted with a Pertronix unit/vacuum advance in it works VERY well for me on the street...CHEAP, dependable, Stock appearing fire. And once I have GMC Bubba set it up for my Blower, it should be right up there with the best...for the street...:D

  19. Simple is good for me.

    Im gonna run a recurved, mech adv SBM elec dist, with a MSD 6BTM to allow me to dump timing as boost rises on a blown 330 Desoto.

    Anyone care to offer dist timing curves/initial and total figures for a pump gas, 6-71 blown Hemi?

    Rat
     
  20. FRANKIE - I'd sure be interested in that curve info, too...just for my own curiosity. Sure wish someone would do a Curve Tech on the subject...

    I think that your initial will be a 'develop as you go' kinda deal based on all of the particular details of your package. The max should be held to 36 deg or so. In the old days we were breaking cylinder walls with hi boost and totals over 36...maybe someone has current trend info to share.

    Now you have the best of all worlds all you need is our new "Bubba" coil for the HEI.
    At .3 ohms it drives the current limit of the HEI controller where it should be at 5-6 amps of current..:eek::D

    Just a note here guys.
    If ya have stock old hemi cast iron distributor AND a correct rotation later electronic distributor. The inside upper shaft and parts will fit from one to the other including the reluctor,pickup and upper place etc.
    You now have the late electronic stuff inside the older "ols school" housing .
    Wire it up to a hei module the right coil and its the best available.......

    Not quite Bubba. Holes are in the wrong place and if you aren't careful it won't be clocked right for the cap.

    WOW i have done two just over the last few months and both are running great with happy customers.
    Now see what youve done , now i will have to get in the core box and actually check rotor index etc.??????????
    I must have been lucky or just had the rotor off enough to cause high secondary voltage but no too high .
    Thanks for the comments .

    I will lay another one out and do a rotor index..........hamb is the greatest!!

    On the one I tried you could put the screw in one hole of the breaker plate mount but the other would not line up. Perhaps I chose the wrong one. It's been a few years but I vaugely remember making a mod to the vacuum advance as well. If it's really that simple I should have a go at it again.

    Well, my first generation supermag isn't hot enough to throw a spark at cranking speeds. Tried to fire the digger the other night to no avail. Instead of doing a basic rebuild on it and hoping I've got Spud at Fuel Injection Enterprises hot rodding a Vertex for me to make around 3 amps. It's gonna hurt the wallet but I think getting one done by the right guy is the way to go in my case.

    I bought the core from his as well but it doesn't include the drive. Anybody out there have a cheap early hemi, small block Mopar drive for a vertex? If not for the right app how about a cheap sbc/bbc drive?
