OK, so after 100 hours of troubleshooting it looks like it is the ORANGE BOX. I waited to change it out because it only had a few hundred miles on it, so I couldn’t believe it was the box. But thanks to XCuda and 540Cuda, they pointed out I put my box on the engine (to hide it for OEM look)...

OK. That helps me narrow down items to look at. Thanks

Guys thanks for all the tips. Will check all that out. I put a new Carter fuel pump in. bypassed the vapor separator. I did not yet check the fuel pressure with the new pump (i just ordered a new pressure gauge in case my old one is off) Took the car around the block and it’s still bogging...

Thanks so I’ll check pump/separator and orange box and then vacuum advance.

Yes it’s on the engine because I’m going for OEM look and was not going to drill holes on the firewall. I do have another box I could try. BTW recommendations on best quality box currently on the market? Eventually I could hide it under the battery tray? Or is that also a lousy spot due to...

Ya, don’t mess with those original panels. Irreplaceable. Maybe find a washer or smooth metal piece that’s tiny bit larger than the cat whisker metal channel. Put the washer/ metal piece in a vise and then pull the whisker over the washer/metal piece slowly to open up the channel. Challenge is...

Thanks X

The 1970 are push-on clips for the “door side”. 1971 are screw in (I found this out the hard way). But on the door panel I kept my originals and didn’t try installing the new cat whiskers. I could see though it could be a challenge getting them on the top edge of the panel. Are your door panels...

I may not try the gas can method so I don’t fry the Chally, but I did order a new Carter mechanical pump to try. My original vapor separator may also be the culprit, so I will try to bypass it and go direct from the pump to the carb. I did switch between a mechanical points distributor and an...

OK, so I shortened the tube going to the gauge. Ran it again. At idle the needle still bouncing a bit, but averaging about 4 psi. As I increase the RPM the pressure starts to drop below 4 and head toward 3 psi. Is this running too low? Maybe I still am not measuring the pressure properly with...

OK, I just realized the hose to the gauge is too long and filled with air. The air pocket is like a spring and causing the dial bouncing. I’ll try again with the shortest length possible. In the meantime any advice on the fuel pressure is highly welcome, Thanks

Been having trouble with the engine. Runs great at idle, but as I accelerate from about 2500 RPM and above, the engine bogs down badly and loses all power. But then back to smooth running at idle. Please note: in the driveway, when I pull the throttle and get above 3000 RPM I do not hear or...

Thanks for all the input !

Looks like the vapor separator does its job…. But my question is did the 1970 440 engine also come with a fuel filter after the vapor separator? From the factory. It’s confusing from the manuals and resto guides

I finally pulled out the service manual but of course its very confusing. In the “Maintenance” section is show a fuel filter, but not the vapor separator. In the “Fuel” section is only shows the vapor separator. My Dave Wise manual is not clear if there is a filter, or not. Can anyone...
