I’ve got a low mileage quickfuel Q-series ban-750 blow thru carburetor for sale. Low mileage, never been taken apart. Factory settings with the jets and air bleeds. This is a 900 dollar carburetor with under 2500 miles of run time on it. Asking 675.00 shipped. If interested send me a pm, thanks. I h...

What else could is possibly be? Compression is great on all 8 cylinders, 155psi on the dot on every cylinder. Engine vacuum is steady at 20hg idling, I just don’t understand what else it could possibly be. It’s not ignition, it doesn’t appear to be a mechanical issue inside the heads with such good ...

I think I may finally figured out the issue, or at least I hope I have. I called and spoke with a guy at AED performance carburetors because I was inquiring about a set of metering blocks they have because Initially I was thinking there was a manufacturer defect with my quickfuel metering blocks. An...

I believe I finally figured out what’s going on!! It’s not ignition, it’s not mechanical, it’s fuel related! I think my quickfuel carb is giving cylinder 6 too much fuel to where it’s so rich it’s causing a missfire. Has anyone else encountered this before? I realized that sometimes if I step on it ...

What are people’s thoufhts on it possibly being the distributor/ oil pump drive gear bushing? I’ve read online these can go out and cause a lot of issues with ignition. I’m starting to consider that as a possibility seems how every last piece to the ignition is brand new and I have good compression ...

Put the brand new plug inn on cylinder 6 and it’s still missing like a sob. I’m convinced now there is an issue with cylinder 6 somewhere possibly cylinder 8 as well. I just don’t know how to diagnose the problem. I’m thinking ether a valve or valve spring or a broken rocker arm or push rod. Somethi...

So this afternoon I finally had some free time on my hands. I pulled all the spark plugs out and cylinder 6’s plug is carbon fouled, black soot looking substance on it that was dry, almost how the inside of a chimney looks. So I’m sure that was causing the roughness I was feeling under load going d...

Disconnect the exhaust from where it is attached to the chassis and support it on stands or whatever and check if it fixes it. I have seen first hand that this can cause a vibration at certain revs. I’ve dis-connected the exhaust before, and the alternator and ps pump belts, I’ve took the radiator ...

I'm not familiar with Mopar drivelines, but could you unbolt but not remove the converter and briefly run up the engine to see if the vibration is affected? Unfortuently no, you can’t un-bolt the converter and slide it back like you can on a small block Chevy or else I would have done it already. I...

Upon re-reading the post, nowhere does it say the vibration is a recent development; it may well have been there since the new engine was installed, making the flywheel a likely culprit. There is mention of a 'magnum balanced converter'. Does a 360 need both unbalanced? If the converter has deliber...

I haven’t gotten a chance to mess with the truck this weekend, the weather decided to get super nasty Friday night and it’s stayed all weekend. It’s negative 9 right now, and it snowed another 12 inches. And I don’t have my garage organized enough to pull it into the garage cause I just moved into t...

They make insulated pliers, it's a quick way to find a weak dead hole. You can also use a test light,ground the clamp lead- lube the probe with dielectric grease and go between the boot and plug wire on the distributor end of the wires. Just trying to help. John I have some of the insulated plug wi...

In my post above I advised to hold the rpms at 2500 and remove one plug wire at a time. When the plug wire is removed , note the rpm drop for each cylinder. They should all drop aproxx the same rpm. The one that barely drops is a cylinder that needs looked at. That test is called a power balance te...
