It says they could have up to twelve heads. I hope she isn't too evil.
I wonder if those 12 heads could be represented with 12 exhaust pipes sticking straight up.
Thanks for the name.

better go like a mad sientist saying its alive its alive then runnin around like dexter screaming my hair is on fire my hair is on fire

neev_nav · 11-27-2007, 03:03 PM

That's awesome! Can't wait to see/hear it run.

cayoterun · 11-27-2007, 04:12 PM

BALAUR, attempted flight, low batteries, cold weather. Practicing posting videos. Failed for today. Tried 27 ways that didn't work. These motors were notorious for being hard starting.
It's name for today was-- Oh baloney.

When I scatched her name with soapstone on the surge tank, wiped the dust off, and it had anti-freeze checked 10-31-85 with tire chalk, so we know she was in service then. 21yrs not bad.

Well, now I know how the dog feels that caught the car.----What are we gonna' do with it?

The vapor coming out the radiator outlet is not a sign the motor is hot. Probably just gunk getting hot next to cylinders in water jacket.
I was able to hold my hand on the exhaust manifold when we shut it off.
Sounded good, had 40# oil pressure and was burning propane.
I think the name just fits.
Next is rig up a temporary radiator, lots of tinkering and matching a clutch/tranny.
Thanks, everyone,
Cayoterun

watahyahknow · 11-28-2007, 04:52 PM

i sounds good , i do notice that one of the exausts is blowing a little more smoke then the others

cayoterun · 11-29-2007, 09:52 AM

I don't know what to expect from it. About anything might show up. When we get some kind of cooling hooked up, we'll learn more.
I sure want to put some hrs of run time on it in the stand before going too much further.
The length of this video is the longest it has run, and we thought that was plenty.
Thanks,
Cayoterun

Storm Chaser · 11-29-2007, 10:06 AM

I'm about to utter the phrase that usually ends up making me broke...

I want one!

cayoterun · 11-29-2007, 10:18 AM

I'd still like to see someone build a T-bucket type rig that has the motor exposed.
Keep thinkin', Storm-Chaser
Cayoterun

Storm Chaser · 11-29-2007, 12:52 PM

Heh, my thinking gets me into trouble... I'm currently working on a picture of a late 30's-early 40's military truck with an Airstream camper attached. It's just for fun though, I don't plan on building it.

Funny thing... about 3 years ago I toyed with the idea of welding a CJ5 front tub to a CJ7 rear to make a 4-door Jeep... Now you can go to the dealer and get one new. I also wanted to put a VW body on a Jeep chassis, and have a Chevy V6 hanging out the back (called it Project Cockroach).

But yea, I'd really like to build a T with a twin six someday. If one of those engines ever comes up around here and I can afford it, I might have to grab it up.

Mickey_D · 11-29-2007, 12:53 PM

If gas wasn't so expensive, I'd take you up on that. It would look cool as hell in this....

And that thing is still parked out there, so I could probably get it relatively cheap now.

You're giving me ideas here. STOP THAT!!!!!

jeffspower · 11-29-2007, 07:13 PM

That thing is going to have an awesome sounding idle. I bet with full exhaust and a good tune, it will be smooth as silk at less than 400 rpm. Sounds pretty responsive for having a crankshaft & flywheel that weighs more than some of today's complete engines!

68K20 x Drill · 11-29-2007, 07:23 PM

That is just GREAT!

cayoterun · 11-29-2007, 09:26 PM

The only new parts I put on the motor were both distributor caps , rotors, propane diaphrams in carbs, and gaskets/w a used head.
I did that for braggin' rights on behalf of their durability.
Today, it got new coils, points, & condensers. I didn't put any themostats in it, hooked up a garden hose, ran another hose from water pump out door. Circulated clean water thru it for about three hrs. Lots of rust and junk came out.
I have 10-30 oil in it, thinking that might go thru oil passages better. They normally run 15-50 in them. I don't plan to wind it up much for awhile, then change to heavy oil. Timed it with a light, and the longer it ran the smoother and quieter it got. The right front bank has about quit smoking.
Keep thinkin' on those open motor projects.

Fuel consumption: It used about 5 gallons of propane in about 3hr run time. I guess it takes fuel for fire & smoke, tho.
Thanks,
Cayoterun

watahyahknow · 11-30-2007, 02:33 AM

the latest creeation from the blastolenes has a gmc v12 in it btw
http://www.blastolene.com/b702_f.html
they made the tankmotor powered rod for jay lenno too

cayoterun · 11-30-2007, 05:29 AM

Approximate mileage equivalent. These could be very realistic numbers, annual run time could even be more.
24hrs X 7 = 168hrs per week X 26wks per year =4,360hrs per year X 60mph = 262,080 mi. per year X 21 yrs service = 5,503,680 Total equivalent miles on old "Baluar". No wonder she has a contankerous attitude. So if she drinks oil, rattles, smokes, clunks, and complains, I figure she earned her dues.

Ck my 'rithmatic
We do know it's been long blocked once and probably valves more often.
All motors run much longer pumping than in vehicles.
What is it? Constant rpm, temperature, oil circulation?
Cayoterun

watahyahknow · 11-30-2007, 05:38 AM

prolly the fact it runs all the time so no loss of oilpressure on shutdown and startup , it keeps its temperature , and i guess it doesnt had to work over 60 % of its total power driving the pump back in the days

Storm Chaser · 11-30-2007, 10:06 AM

I couldn't help myself...

cayoterun · 11-30-2007, 11:30 AM

My Gosh--Awsome--wild-- best ideas yet!! Don't paint nutin' but, maybe?, motor?? Can you add 12 chrome stacks? One off each cylinder sticking straight up.
Now, that's my idea of a real hotrod from the '50's. That looks like something straight from 40 yrs in the scrap yard and brought back to life.

If Mama don't take away our ideas and crayons, we'll all be in deep trouble.
If I take some pics today of the trucks, would it better to post them here or send PM, and could/would you tinker with them on this same idea? I'm kinda stuck on my '62 GMC cab (at least) because of the current tag and title.
Cayoterun

cayoterun · 11-30-2007, 08:22 PM

The '62 pickup pic stinks. I'll go take more in the morning. I'll try to get the hood sit on it if the bum back will let me. It was a good time of day for the 1ton.
I'd like to set the cab and front clip from the pickup on the '79 1ton. Slide pickup cab back and extend clip back two feet and use same 1ton flat bed and frame/w bed chopped two feet. That would leave us 2 feet shorter bed and 2 feet longer front clip.
Also, add tool boxs both front & back of wheels under bed.
If someone wants to, tinker with no front clip & open motor.

Someone may ask, why change? Pickup has tag and title and personally, I won't sit the engine on a suspension lighter than a 1ton. When we get the engine, clutch,tranny and all combined, it will probably weigh 23-2400#

Run 2 more hrs on "Balaur" today. Running better.
Thanks,
Cayoterun

cayoterun · 12-01-2007, 02:04 PM

Maybe a better pickup pic w/ hood
Thanks

Hi, I've been following this thread for months. Here is my take on your truck.

watahyahknow · 12-22-2007, 09:12 PM

try sending an email to the blastolene brothers there newest car has the same engine in it and they prolly can tell you wich trans will work .
its originally based on a 6 cylinder gmc so i wouldn't be surprized if that gearbox matches the block

dwcsr · 12-22-2007, 11:30 PM

If you can get hold of a Sundstrand Hydrastatic transmission they will bolt up to the V12. They used them in some trash haulers in the 70's
