Located a y-block starter (I am told) for our project engine. Are they all interchangeable or do I need to look for a certain one? We are using a 272 block, what about the bellhousing (we dont have a trans yet but are supposed to be getting one from the same place as the starter, no idea if they came from the same vehicle, probably not) I imagine before I can determine this I will need a trans and bellhousing to if they mate up?? Any tips or tricks to improving the starter or do they work as best they can with just a standard rebuild? Thanks-
