Their 2K paint spray can products indeed seem better than your typical 1K spray can paints. I did some wheels, last year, and they sat on the deck in the weather and still look good (after cleaning)
in a three-letter code, the first letter denotes the applicable year. FM3 (where E=1969, F=1970, G=1971), M3 refers to the color. M-3 is not there on the 1971 paint chart, but is on the 1970 chart
A dyno plot of the horsepower and torque curves will show you where, and how much power it makes across the RPM range.
At the wheels, this is best done with the factory torque convertor (TC) that locks earlier than later.
For improved quarter mile times, you may want to shoot for a TC the...
I've driven several 440 cars over the years, and I can share a few thought about what I think I know.
Sometimes, engines can have all the right parts, and just don't produce the power you would expect. They may have a better intake, higher CFM carburetors, header exhaust, perhaps ported heads...
If you're looking at the date code, just make sure its a month or two before the production date on the door sticker. I looked at that carb on ebay, and it looks like someone spent a lot of time cleaning it up and making it look nice(r)
The parts books shows the AVS carbs issued with the 340-4 was absent on CAS cars, present on ECS.
That said, my observation is the majority of vintage AVS carburetors originally equipped with these solenoids will be missing them. It's on the rare side, the used carb is sold with the solenoid...
the existing wiring harness may be brittle. the insulation gets dried out, and handling can cause cracking and breakage. if you're set on replacing the wires, you may need to detach most of the driver size of the headliner to expose the existing wiring routing over to the sail panel.
if your headliner is vintage, it may be brittle and tear easily. even so, you may be able to detach enough of it to expose the wiring harness. Ronbo73 is correct, fishing any wires over to the dome light will likely be in contact with the headliner and be visible.
in my opinion, you won't need a 3/8 fuel line, and 5/16 will be just fine. that's the way it came from the factory, even on the 6-barrel 340 motors.
and your existing 3/8 sending unit with a plugged return line will behave just like the other sending units without a return line.
if you're...
