Reg Evans Posted April 2, 2016 Share Posted April 2, 2016 Maybe someone here needs this for their 25" flathead. http://www.ebay.com/itm/121941705251?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649 Thanks Link to comment Share on other sites More sharing options...

Reg Evans Posted April 22, 2016 Author Share Posted April 22, 2016 No problem. Hey...why is your handle Silverdome. What you driving ? Link to comment Share on other sites More sharing options...
Silverdome Posted April 25, 2016 Share Posted April 25, 2016 When I was younger my nickname was Copperhead because of my fiery red hair now that I am older it's more silver. My dad raised me to be a MoPar man and when he died he left me some old cars and of course you probably know that Plymouth used the term Silverdome to describe their engines back in the day so I thought it better described what I look like nowadays. He left me a couple of 34 Dodges and a 48 Plymouth and I also have a 66 Plymouth. Link to comment Share on other sites More sharing options...
Reg Evans Posted April 25, 2016 Author Share Posted April 25, 2016 Oh...Ha Ha Ha. When I was growing up I too was a Copperhead. My hair has also turned more silver than copper. Yes, I have a 1933 Plymouth and am familiar with the term Silverdome. There was a high compression head that would boost the HP to 77...... up from 70. Sure wish I could find one ! Attached is a photo of the only silverdome I have so far. Link to comment Share on other sites More sharing options...

Reg Evans Posted April 27, 2016 Author Share Posted April 27, 2016 You are correct and I made another error. The red head added 6 more horses,not 7. But after all these years the read head has probably turned silver too. Link to comment Share on other sites More sharing options...
Silverdome Posted April 29, 2016 Share Posted April 29, 2016 Reg, Could you download the pictures here? I went to the ebay site and tried downloading them but it didn't work. I may attempt to fabricate similar ones in the future and these would be a great reference tool. Thanks, Mark (AKA Silverdome) Link to comment Share on other sites More sharing options...

Silverdome Posted May 2, 2016 Share Posted May 2, 2016 Thank you so much. I've had that basic design in my mind for quite some time now. I would probably make them a little lighter in weight though. Is the cross bar between the carburetor risers for linkage or strength or both? Link to comment Share on other sites More sharing options...
Reg Evans Posted May 2, 2016 Author Share Posted May 2, 2016 Oh.....that's a balance tube. Link to comment Share on other sites More sharing options...
Silverdome Posted May 5, 2016 Share Posted May 5, 2016 So that hole in the center of the balance tube would be where the vacuum advance would hook up to pull equal amounts from each carburetor? Link to comment Share on other sites More sharing options...
Reg Evans Posted May 5, 2016 Author Share Posted May 5, 2016 This setup was used on larger Dodge trucks and I think that port was used for vacuum assist brakes or a 2 speed rear end. The vac advance could be operated from one or maybe both carbs. Hey.....Look here. http://www.langdonsstovebolt.com/ 1 Link to comment Share on other sites More sharing options...
Silverdome Posted May 6, 2016 Share Posted May 6, 2016 Thanks, those look pretty cool. Did you read the part about the heat plate needed? It seems a lot of people forget that you have to atomize or vaporize the liquid fuel for it to burn efficiently. That's why I liked the look of the manifolds that you posted because they address that issue. Link to comment Share on other sites More sharing options...
c49er Posted May 6, 2016 Share Posted May 6, 2016 No vacuum advance was used on the 2-1/2 ton dual carb twin exhaust 265 engine. As mentioned the the intake balance tube port supplied vacuum only for the optional 2 speed rear end and the required brake booster. Bob Link to comment Share on other sites More sharing options...
