I am tired of trying to get my original Carter 3705 carbs to work correctly and will send them out to be restored. Mancini sells a crossram kit with the intake and edelbrock carbs, but I don't need the intake. If I wanted to run Edelbrocks or some other carbs for now, which ones would you...

On my max wedge manifold, they added a vacuum tube to the PCV valve connector as shown in the photo attached. They had it blocked and were not using it (stuffed a bunch of scotch tape into the rubber line). I am trying to use this for manifold vaccum on my vac adv distributor from Summit. It...

Have issues with dual carter 3705s on wedge intake running pig rich. Cam is 509. Following everyones tips here I bumped up initial timing to get vacuum up, changed metering springs, etc etc. Still pig rich at idle and even part throttle. So today I decided to pull tops and check float levels...

Rebuilt my two Carter 3705s on max wedge intake using kits #4051A from quadrajet parts. Noticed the base gaskets were different in the kit from what were on them when taken off the manifolds. It looked like there were vacuum passages on base plate where on old gaskets they were not covered but...

I bought a Holley 12-840 fuel pressure regulator to use for testing excess fuel pressure. It has 3/8 NPT on all three ports. My max wedge has metal fuel lines coming from the mechanical pump and from the brass tee that are all 1/4 npt male flared fittings. Don't laugh as I'm no fuel line...

I have a max wedge tribute car with factory wedge crossram and two Carter 3705s. Carbs have been rebuilt and I am still way rich at idle (but this could be the 509 cam's low vacuum at idle). Mechanical fuel pump (factory style replacement) is putting out 6.5 lbs of pressure. Could that be too...

I bought a new speed demon 750 VS and can't seem to get it tuned correctly. It had a quick fuel power valve n it out of the box so I suspected it might have been a return, but Holley said they use QF parts when building them since they are interchangeable. But now I see the main jets are 74's...

Thanks to the folks here on the forum I now have my AC working and my Speed Demon plumbed to the factory steel line. But now I have another issue I need help with. I had a throttle kick up bracket from my street demon that worked fine, but it won't mount to the Speed Demon. I have also tried...

Just put a speed demon carb on my 63 polara using their dual line braided connection kit. I have never worked with braided or AN fittings before so please bear with me. The original metal line from the tank is flared with a fitting on it that screwed into another metal fitting with a very stiff...
