Hello Everyone. I am new here but am looking for a lot of information. I have a 1989 Bronco II with the standard 2.9L V6 and its an automatic 4X4 unit. Anyways, a long time ago the oil blew on the engine and to my understanding the oil pump is internal. I wanted to ask if anyone knows what size engine I might be able to bolt up to my existing transmission. I would like something bigger than the 2.9L that is there. Any help is much appreciated. Thanks in advance
