A friend has an engine lying in his shop,that had been in a street rod of some kind.We can`t identify it.I tried online,to no avail.It is a 4 cylinder with two covers on top(valve covers,probably).Carb is on the left side,and exhaust headers are on the RIGHT(take note).Does anybody know what engine this is?The engine was removed,before my friend got it,and replaced with a V8.It`s supposed to be a good engine.Maybe a sprint or midget engine?
