I can't find any reference to my engine which has a 1850 american tall block modification?

Question

What is it more commonly known as, as I can't find any references to it on the internet and I want to know where to get piston rods, head gaskets etc. It's in a Ford Orion and looks pretty much like the standard stock engine.

The 1850 refers to the CC as it's been rebored to 1900cc

Answer 1

i own a shop, and have worked on vehicles for many years now. I have no idea what you are talking about. I have heard of a tall block, and a regular block. One thing that comes to mind is a tall block 400 being mistaken for a 460 cubic inch engine. When you say 1850, what are you talking about? 1850 what? You can get the parts you need, but you will have to find someone who can measure out the parts, and determine what this is in English (American). A good place to purchase parts from is www.northernautoparts.com
They have about the best prices on parts in America.
Part2:
Ok if I'm reading you correctly you have a 1900 cc engine. You must be talking about using a shorter piston, and a longer rod? Is this a solid block engine, or one that uses jugs & pistons, as in an air cooled engine? In order to get the rods you will need, you need to measure the rods from center line of the crank to the center line of the wrist pin. You will need to measure the piston from center line of wrist pin to the top of the piston bore. Keep in mind you cannot go all the way to the top of the block with the piston. You must leave at least .050-.080 of an inch for clearence. The engine being bored to a 1900 does not change the stroke on the engine, and you should be using the same length rods as what you have now. If you will measure the (ID) inside diameter of the bore of the piston wall, the diameter, the wrist pin size, and the distance from the wrist pin to the top of the piston, and contact www.kbsilvolite.com/ You can also measure out your rods, and contact www.eaglerod.com or any other rod manufacture. What you are trying to do isn't rocket science, and if you contact the correct companies (the ones that manufacutre the parts) you can come up with parts for any kind of engine made. Just because the engine has been bored doesn't mean there is no pistons made for it. There may be five or six different engines that use the same piston. The measurements, and the numbers is what is critical when one builds any engine.
Glad to help out, Good Luck!!!
