Been shopping online to buy a complete engine overhaul kit for a 1984 Ford 5610 diesel. I see advertised prices but can't seem to find any information on who or where they are made. I need a new crank and some tractor places advertise $300 less than others. I have emailed vendors to try and get some info with no response. Today I called yesterdays and was caller number 23 waiting, waited 45 minutes and was down to caller 14 when I had to go. Wondering if the crankshaft is made in china and how the pistons and parts in the engine kits hold up. anyone ever bought a engine kit or advice on aftermarket vendors? Hard to find any reviews
