Many, many thanks to
@JDMopar and
@RAT ROD AL for their combined effort to send me a vent tube for free, which was missing on my Barracuda. I really appreciated that. Too bad I had to take half the car apart to get it in there. Oh well.
I bought a used 500 cfm Edelbrock AVS from a local FABO member. Unfortunately the throttle lever was cut off so I couldn't attach the kickdown cable, so I robbed that off my 600 cfm Performer as well as the electric choke, which was missing on the AVS. Initially I saw quite quite a jump in gas mileage, but I'm still fiddling with it. Then somehow my throttle cable broke at the fire wall. When I replaced that I took out the driver seat because it's no fun to work under the dash with the seat in. I had noticed that it felt like I was sitting lower as usual and unfortunately two of the springs are broken. I used some zip ties as a temporary fix, but that lasted about 20 minutes. Now I need to find a seat frame bottom...
Speaking of seats... When I took stuff apart for the vent tube I had to take out the back seat bottom because I dropped some screws and they fell in the crack. While it was out I figured I could fix it. Most of it is in good shape, but the seams came apart in a couple of places. So I took the cover off and started going through the original holes with some upholstery grade thread.
Especially the passenger side bottom corner had a couple of rips, so I sowed a patch on.
I don't think it's going to be very noticeable and I plan on spraying them with Vinyl paint when I'm done. The frame has some rust that I want wire wheel and paint and some of the sleeves that the hog rings attach to are in bad shape, so I still need to figure that out. I have a very nice black top/ back cover where I already fixed the stiching, but I will put it on the frame first before painting that red too. That Duplicolor vinyl paint covers pretty well.
I got some pinging when I stepped on the gas, so I took out and swapped out the springs hoping that the full advance would come in a bit later. Luckily I didn't have to take the distributor apart at all. One of the springs didn't engage at all with the limited advance and the other wasn't very strong. There was still a little bit of pinging when I really stepped on it, so I reduced the timing a hair more and it seems fine.
Like the title of this thread says, this car is driven daily. So fun.
