Question:

Iron content in sand. What percentage is considered high?

I‘d like to know what percentage is considered high in sand (from river) with traces of iron?

A surprisingly low iron content is considered high in sand. Most silica sand certainly contains less than 1% Fe2O3. A sand containing 2% would be brick red. The reddish or yellowish colour of quartz sand is often the result of a grain coating of iron hydroxide, but even a small percent(0.2%) will give a straw yellow colour. Sand suitable for glass making is generally less than 0.015% Fe2O3. If it contains a lot of rock fragments; particularly derived from basaltic rocks, the iron content could be higher, and the sand would appear to be black or dark grey (basalt contains about 20% Fe2O3). Then of course, there are heavy mineral sands (valuable, because they contain the minerals ilmenite, zircon and rutile) If they contain a lot of ilmenite, they will also be black. A pure ilmenite sand will be dark black and contain about 30% Fe2O3. Then there are some sands high in magnetite (Fe3O4) that are mined as iron ores. A pure magnetite sand will actually contain more iron than in Fe2O3.
As long as you have a '86 or newer engine with the one piece rear main seal the flywheels will interchange. Your original torque converter will work fine.

the 305 and the 350 has the same transmition mount bolt holes there is a flywheel on a 700r4 tranny that is different but most all are the same good luck
