Main engine bearing compatability

[Richb77]

Hi all.

I am looking to buy a set of main engine bearings (the shells that fit around the crank shaft into the block) and wondered what the compatibility between engines was like.

I have a 1600 681F mk2 cortina engine and have spotted a set from a 771m Fiesta XR2 engine and wondered if they are technically the same.

If not can anyone recommend a part number/brand to search for? Cheers.

They should be the same !
