Guys need some info on ford seirras as have the chance to buy one and dont really want to pass it up.. The guy says it used to have a 1600 engine if so where they a special 1600 only made for the seirra? Or where they the same as escorts or cortinas.. He says he has a 2 ltr guessing a pinto question is is it as easy as the escort 2 ltr conversion ? And finally if anyone has a seirra 1600 engine for sale let mee know pleeassee
