*UPDATE*

IT LIVES!!!!!

Well, this was the big weekend. I started off by building up the exhaust..







Then I got the fuel system plumbed up..



Then Sunday, we all (Me, Julia and the boys) headed up to the shop with my best friend Dan to meet up with Chris, Melissa and Carston for a small "Firing Party". The boys had a great time pitching in...







Julia, being a wonderful "shutterbug" snapped a bunch of great pics..





Me and my best friend Dan playing with the "Special"



My "big brother" Chris and Melissa playing around..



Then after much tweaking and fussing...

Clayton - For an engine that probably needs a bit more adjustment in carburetion, that's about the sweetest sounding "music" I've heard in a long time. Wonder if there's a way to make that some sort of "background music" here on the forum,...ha,ha.....

Ya' really couldn't ask for a more steady and even idle, but from the way she acts when you crack the throttle Clayton, my first guess would be that she needs either a bit more accelerator pump, or maybe a bit less. Idles beautifully, and runs smooth and steady at higher rpm,....once it gets there.

Knowing your attention to detail and perfection, I'd guess that the accelerator pump(s) work just fine, but maybe even one carburetor's accelerator pump, pumps a bit to much for a little "4-banger".

Don't know why I even suggest any of this, because there are many things that could need a bit of a "tweak", and knowing you Clayton, it'll soon be running "smooth as silk"!

Come to think of it, if all else fails Clayton, disconnect the accelerator pump and then crack the throttle on the one carb and see how she acts. When you think about it, a stock Model T carburetor like the NH Holley doesn't even have an accelerator pump!

Okay,....I'll "shut up" now Clayton; I should know what you've forgotten about engines, right?

I still think that idle with that exhaust system you built sure sounds sweet. Thanks for sharing all of the build photos and the great video with us Clayton,.......harold

It seems to be running well! That's better than I could guess mine would be if I had that many modifications. Amazingly you got it to running smoothly the first time! You must have had some coaching to be able to do that. It sounds very good to me.

Good luck.
Norm

Harold,

It is a very sweet sound indeed!

I certainly do have some carb tuning to do that is for sure. These 2 Stromberg 81s were custom built for this motor and detuned to function as a pair on this engine. The gentleman that built them is a real craftsman, but only set them up for the basic air/fuel mixture. Needless to say, I have a some involved tuning to do. I am very happy with how easily it came to life though....and it even cranks starts super easy now!

The exhaust truly does give it the right attitude, the old torque tube back half of the exhaust is the key......and that nasty cam :-)

Norman,

I really expected her to put up a bit more of a fight....but I guess that means everything was done right. To be honest, all I did was put gas, oil and water in it and hit the starter :-)

Sounds sweet. A bit of dialing in those carbs, and you will be smoking those tires.

Clayton, Congrats!!! She trully is a beast.I love the exhaust. It produduces a trully wonderful sound. You still may make me a believer in those dual carbs yet.That being said, I will offer my 2 cents on the acceleration issue.In listening to the video, it seems you are lacking on the low end, but have border line to excessive on the top end. So that being said....If I were to approach this I would think about getting the mechanical power valves in those 81's to open sooner, and after I took care of that I might consider jetting it down on the top end. I actually prefer the holley 92-94 carbs because you can change the power valves and correct this. I realize there is all kinds of hoodoo about 94 style carbs but they really do work well when you get your head around everything. The thing is; You have to keep in mind, you only have 170 or so cubes, so the vaccum signal drops quickly. This happens especially fast with the dual carbs so they need to open sooner. Again my 2 cents. All that aside you make us all proud. Again, congrats.....Thanks, John M.

Clayton, I would have to clarify.
With 170 or so cubes the power valves need to open sooner....Thanks John

Not much to add Clayton except, I LIKE IT!! It sounds knarly


Top of pagePrevious messageNext messageBottom of page Link to this message  By Tim Williams on Monday, July 23, 2012 - 11:01 pm:

sounds good clayton. I like it. Now if i can just figure out why mine is only running on 3 cylinders, I think I have a valve sticking issue.


Top of pagePrevious messageNext messageBottom of page Link to this message  By Clayton Paddison, Portland Oregon on Tuesday, July 24, 2012 - 12:32 am:

John,

When I had these 81's built, they were built specifically for this motor and those are both points that we discussed in great length. The main jets were reduced and the power valves were changed for specifically the reasons you mention.

Since the video, the car did begin to run much smoother then we see here on the first fire. The carbs will need some tuning still, but have faith that they will preform beautifully.

BTW, I don't think it's 170 cubes anymore....since it is opened up .080 over :-)

Scott,

Totally gnarly! :-) the header and the exhaust make the sound, but the cam is the key.

it is WAY louder then the original motor!

Tim,

Just take the valve cover off and roll it over by hand....that will tell you right quick :-)

You gotta come over and hear this thing though..

Thats what I am going to do. hopefully wednesday I will have some time. I want to hear that run, sounds good on the video.

Great sound & great smile on your face after the test drive :-)

The exhaust pipe looks very solid. You may want the rear exhaust bracket flexible in the pipe's lengthwise direction, so the heat expanding pipe can grow and shrink without putting unnecessary strain on the bracket and the front flange.

Hey Clayton there was a gadget called a 'Unasyn' (spelling may not be correct) it's kind of a vacuum gauge that sits on the top of the carb and came in really handy when adjusting multiple carbs back in the stone age. I just went to the Net and tried to find a link to one so you could see what I was talking about but I couldn't find anything?
Maybe some of the guys here know what I'm talking about, and can find a link to one?


Top of pagePrevious messageNext messageBottom of page Link to this message  By Clayton Paddison, Portland Oregon on Tuesday, July 24, 2012 - 12:41 pm:

Dennis,

You wouldn't be talking about one of these guys would you?


Top of pagePrevious messageNext messageBottom of page Link to this message  By Dennis Halpin on Tuesday, July 24, 2012 - 08:28 pm:

Yup. I guess you've got things covered. The 'Olde Fart' will go back to taking a nap and let you young 'Whipper Snappers' carry on. :-)
That engine sure sounds right. I'm interested in seeing what color that exhaust manifold turns and where, after a good long 'hot lap'.

Congratulations on your first lap of the garage! Looking forward to another video, better get to work!

John

Dennis,

Things are far from covered, but thanks for the vote of confidence :-) I haven't really messed around with one of those yet, so it will be fun to learn.

...Kinda hoping that manifold stays that pretty blue color personally.

John,

Thank you kindly! If all goes well, the plan is to take her out for a good run this weekend. Plenty more videos will follow :-)

*UPDATE*
Final assembly work and adjustments..

Since I now have the car in running order....being able to take it out on the street is starting to get at me. So I started in getting all the little things needed to make it "road ready" done...

Like the brake controls and rods..





..the carb linkage would be helpful..



And floors are in the works..


Top of pagePrevious messageNext messageBottom of page Link to this message  By Clayton Paddison, Portland Oregon on Thursday, August 02, 2012 - 02:12 pm:

Just a quick update:

Took her out for a run last Saturday night and it ran like garbage...no power, back firing, had to stay in underdrive the entire time...completely undrivable. On the way back to the shop....she completely crapped out, died in the middle of the road and wouldn't start.

After a tow back home I still couldn't get the thing to fire, so I went through the basics and found she had no spark...."really? Great!" I thought..."Everything is new!"

I came back Sunday morning and pulled my hair out on it some more and got it to fire once, but not for long. I noticed that the ballast resister was hot...and I mean REALLY hot, hot enough to split it open. so I replaced and still no fire....

Everything else checked out with the new Mallory coil being the only thing I hadn't switched out yet. Swapped it out for a cheap 12v coil and it fired right up and has run like a champ since.

...go figure.

I still have some tuning to do, but that motor is a REAL animal :-) It doesn't have allot of bottom end, but it makes up for it with seeming endless top end and tons of power! In overdrive at half throttle she is scary fast!

She has REALLY long legs and want to run!

Aright Clayton, congrats! I sure nice to hear another T owner talk of having some real hp! Your treads have always been very inspiring. Can't wait to hear how she runs on the flats soon. Best of luck to you and Chris.

Mike,

Thank you kindly! It's not so much for me that the it HAS the HP...but more HOW you get that kind of HP out of a T and what it will DO with that kind of HP that interests me and makes it fun. It really makes for a fun car. I'm excited too to see how it does on the trip.

Steve,

I could not agree more...we will certainly do our best to stay as safe and careful out there as possible.

Chris,

That is the first thing I thought the first time I heard it run :-)

Clayton, Would it be possible to get some specifics on that camshaft you are running? By the way, I apologize for being the doubter on your dual carbs It sounds like you have the beast under control....Thanks, John

I know was your saying. Some of my hot rod buddies don't always get it. True you could easily get 300 hp from a small block chev. But to build a little T engine into a 60+ hp fire breather is really something special and demands respect. I have never heard a conplaint after going for a ride in my speedster and I am sure your T will surprize more than a few hot rodders too.

Clayton, congrats on getting your T going. Just remember the coil thing. Just because a part is new, doesn't mean it is good! Have fun! Dave.

So, Clayton, not to seem impatient but....., We are waiting , with bated breath to see what this weekend has brought....

John, Clayton's Cam is a C race regrind. Used to be the top choice of the MT500 crowd for many years. It is .300" lift with 260 degrees of duration all on a stock cam core.


Top of pagePrevious messageNext messageBottom of page Link to this message  By John M mASLACK on Monday, August 06, 2012 - 07:35 pm:

Mike, I have questions concerning Clayton's cam and my old friend Jim Culliunanes idea concerning model A cams. I seek the balance concerning duration and the model t low end torque. That being said,my speedster project is no oil pump with enhanced lube, by way of slingers and main bearing lube by way of a third oil line. So I want enhanced Rpm's at the top end with adequate lubrication.


Top of pagePrevious messageNext messageBottom of page Link to this message  By John M mASLACK on Monday, August 06, 2012 - 08:03 pm:

Mike, After all of that is said,I would like to talk to you about the cam That Clatyon is running and your ideas..... concerning torque and enhanced RPM's
