hi, this has probably been covered before but i cant find it. I have a sierra that was originbally a carbed 2l dohc but the previous owner removed the engine from the car. I have been looking for another twincam but have been offered a 2l from a mk5 cortina (in local scrappy due to scrappage scheme

) that I might go for. I no very little about fords but I believe this would be a pinto? so it should be an easy fit as somer sierras came with these anyway? what parts would need changing to fit this engine and what parts should I make sure to take from the cortina? are the looms the same? I've got all the original parts from my car minus the block.
any help appreciated, cheers.
