What is a cast iron 2bbl intake worth

There is a lot of false info about the 'cash for clunkers' program. It only applied to cars that applied and got the federal rebate. It only applied to the engine and cat converter and possibly the engine computer. Selling the starter and alternator would be ok. The bone yards would have to pay somebody to remove the engine and cat, so for them it was easier to crush the whole car.

I think it was a good idea at the time. More old gas hogs off the road, many of them needing repairs. Had an 60's Olds 88. 425 V-8. Averaged 12 mpg. Worse in winter. Took a long time to warm up. But you could go shopping for a couple of hours and the heater would pour out hot air real soon.
12,000 miles @ 12 mpg = 1000 gallons
12,000 miles @ 24 mpg = 500 gallons [smaller car]
500 gallons times $2.00 per gallon = $1,000 saved

The big crushing took place some years later when the price of metal skyrocketed. Older cars weighing ~4,000 pounds were getting $400 at the boneyard gate! And that is with the tires and gas tank in place.

I think you're right somewhat. But there was a flip side as well. There are lots of youtube videos showing where the yards put that "engine blow up" mixture in the engine of an otherwise decent car and just let the engine run until it slung a rod. These were cars that could have been donated to Goodwill and the like for needy people who otherwise would not have a vehicle. It really sucked to see that happen. I saw it here first hand at a local yard. Once those cars were in, no parts were sold and no cars were sold. The engines were destroyed and they were crushed. Some of them were pretty good cars too. But I do agree the program had its good points, although I believe were fewer than the bad.
