Really enjoyed your carb upgrade. Quick idea: Consider throwing in a fire extinguisher in each time you take a car out. I've seen a couple of fuel line/carb fires with bad results so I always carry a small extinguisher (something like halon, not a dry chemical extinguisher because they leave a residue that's hard to get off after a fire.) Thanks for your video. Looking forward to your next one.
There is one in the trunk! Definitely great advice. Thank you!
Yep, I always have one in the seat next to me. You never ever know when the demons of hell will strike! LOL.
I have my fathers 30 coupe. He was a master mechanic. It has a B block rebuilt by Rod Furtado. Crank, Crower rods and a Dan Price oil pump running full pressure and inserted bearings.The head is a Dan Price 4 port cross flow running a Dan Price cam with dual Stromberg carbs.Exhaust is a Dan Price OHV tube header. '56 steering box and four speed transmission. It is also..... For sale. If interested, or if you know anyone, end a response. Can send photos.
I'd love to see it! Email me seattlespeedshop206@gmail.com thanks!
This coupe is turning out pretty bad ass!
Thanks Matt or Mike! Lol
Hell yeah it is!!!
Cool little coupe! How about a simple heat shield on the pipe by that back carb? Will a "Uni-Syn" tool fit to balance the carbs? I have seen a few dual updraft setups and like the uniqueness. Sounds like it's going to be a good runner.
Good idea! May have to try that! I haven't tried to fit a Uni-sync yet. Hope it fits!
$80 for a quickie $120 for a whole half an hour..... But the memories last forever..... !!!
Nice change to the intro, much "snappier" and sets the stage for the video matter to follow. Also you seem to be getting more comfortable with the narrative throughout the presentation. You're evolving your style in a positive direction. Keep at it............
Thanks Bob! Constantly trying to improve things and keep the pace moving better. Thanks for watching and being such a great supporter!
Back in 1962 my buddy had a 28 A that he installed a 4 Banger with Offenhauser head and cam plus headers. He also had dual down draft carbs. It was a sweet little ride.
That's sounds really cool!
My wife has a really nice 31 Hudson coupe but the Marvel carb was trouble so took it to my favorite carb guy. He said he would not rebuild it for the car because that type was prone to breaking in half then spewing gas on the header pipe. He got me a weber, much better. I also installed 3 point seat belts cause these 8 cylinder Hudsons move well enough for todays traffic. I expect I'll get picked on by some purists but rule #1gotta be reasonably safe.
I'd rather drive it than worry about it catching on fire! I'm sure the weber performs really well! I say it's your car. Do what makes you happy. And damn the purists.
Kind of an interesting attempt at a dual updraft manifold, but that rear carb pulling very hot air from the exhaust down pipe in really concerning. The designer gave that no consideration? Think I'd want a couple of 97's on a downdraft manifold, with air cleaners.
I agree. Definitely not ideal!
I'm not advocating a chop, but back in the pre war era, men, & ladies, wore hats & the roofline was made so that the top of the hat didn't hit the roof lining even on the unmade/bumpy roads of the day. Cars with a "modest" chop can have an enhanced appearance while still looking sufficiently stock to fool all but the knowing. Oh, and your head still does not hit the head lining when driving over modern roads.
Agreed!
Been contemplating doing this twin Zenith carb upgrade cool to see it done and run! Great job
You should!
Had a 30 pickup in high school the most fun car I ever had.
They really are very fun, aren't they?
No instructions or didn’t read first?
Is the air cleaner the front grill? Would more compression run better with modern fuel?
They point backwards, just don't go mudding in reverse!
I don't really know how to answer your fuel question succintly. Modern fuel is a whole video topic in itself. More modern fuels with higher octane ratings generally allow higher compression before detonating as I understand things. From a model A perspective, I think when we talk about modern fuels it's important to consider how inconsistent gas was in the 20s and 30s. Which is my understanding they were designed to run on the worst gas available at the time. Modern fuels are well above those levels. Even without the lead and other stuff. The thing with an A, is even at 7:1, that is well below modern standards. So it's almost like the gas is better than we really need now.
this would be difficult to tune these carbs as there is no accelerator pumps, with such a setup, the velocity in the venturis of the carburetors is greatly reduced so these carbs will be touchy to adjust and very sensitive to weather and atmospheric pressure changes.
good luck
Agreed. There isn't a ton you can do with them. And everything you've said about them being touchy is stuff I have heard before, as well. We'll just have to see how they do. I've got a few tricks up my sleeve. But will save that for another episode.
It’s true yet I’ve read that the intake is a major restriction. I wonder if it would help to stagger the linkage so one carb opens earlier than the other up to about ¼ throttle or so. I’ve had cars with SU carbs which come in many sizes and automatically adjust to changing conditions.
with knowledge, time and money, everything is possible and you can obtain aan acceptable result but it is beyond the reach of most of us.@@allareasindex7984
the SU are a different application, they are constant vacuum style carburetors much less sensitive to low flow conditions
@@garycamara9955
Appears to have some pep on acceleration, but fine tuning required. Looks super.
Yep. Did a carb rebuild and some tuning in the next video. Runs much better
Nice Coupe! What Size of tires do you drive?
@@chschrotter6195 5.50x16 on 16x4 front and 7.50x16 on a 16x4.5 inch rim rear.
Rear fender bob?
Winner winner chicken dinner! We mocked it up a bit, but haven't settled on a shape we like yet.
R u still doing the chop on the model a? Interested!👍
Still trying to talk him into it!
Just found you like your channel and your work Thanks
Thank you for watching!
What sort of highway speed should this setup do ??
Well. A stock A will do 60 mph. This is still limited by the gearing. Maybe a little more top end because of the taller tires. 65-68mph. It's main benefits is the ability to maintain speed when pulling a grade, and quicker acceleration. Without adding an overdrive or changing rear gears, it doesn't really have any more top end speed. Hope that makes sense.
I have a ford model A 1930 and does explosions at a certain time what could it be?
Hard to say, is it backfiring out the exhaust?
Yes
Looking forward to seeing you mount and install the fuel lines. Probably be after the carbs get rebuilt. I really like the look of the coupe.
Thank you! Stay tuned we'll get there!

The carbs were removed from the manifold when we got em. The carbs were open end up and gone thru after we got em. They were just tossed back on the manifold while waiting to be installed…
I don't have any complete 38 rears. But I'll see what I can come up with for ya. You're close on the fenders, but they're not being removed. Hope you guys stay cool down there. It's generally 10 degrees cooler out here vs. The city. Thanks for watching Rodney!
@@Seattle_Speed_Shop Matt ---- I just need to know what the WIDTH is" ----- From drum face to drum face
All your vehicles are nice. I’m very jealous! LOL!
Glad you like them!
Sounded good and wasn't really hard to do .Thanks 😊😊
Thanks for watching!
😀👍️✨
I really like the vintage vibe of this dual intake set up; but it doesn't seem to allow room for exhaust headers which would improve performance even more.
Agreed. Not sure how you'd get a header on it with this set up.
Maybe a split manifold?
What carbs are those?
Tillotson model X
You know you should put some Lucas oil stableizer
I love the wheel and tire combo and the stance of that car.
thanks!
I would love to see the comparison to two Stromberg's 81s. That would be a great video!
OHHH WAIT! I see it is in Ep. #4! See you all there!
We gotta get that on the truck yo compare. Great idea.
How about compression and a cam
It's got a 5.5:1 police head already. And may get a cam in the future.
Thanks for sharing! 😁🙏🏼
Thanks for watching!
You know you take out that boat 🛥 anchor ⚓ and install a nice blown 383 stroker in and then install 2 nice turbos on for even more air flow. He'll yeah
Then it wouldn't be a hot rod...
I keep the SBC's in the trucks they came out of. Though I admit it's possible that this thing could see a 265 or 283 in the future.
