I have never had an LS motor and think I want one

[Bronco Buster]

My 350 is knocking and I am thinking of replacing it with an LS. It seems I can buy a used LS for about the same as a 350 and less than I can build a motor. Can I still run my 435 4 speed or will I need to swap it also? If I can keep it will my clutch and flywheel work or will I need a new one? Has anyone had any dealings with this company http://www.efienginesupply.com/index.html ? If so how are they to deal with? Or does anyone know of another place that sells motors for cheap?

Lkq online. Get you a 5.3 for around 500. Advance adapters will have all the other junk you need for the trans. Personally I would do a auto.
