Humm.. Didn't seem like a smart *** comment to me. Looked like he was just pointing out to use the search button and you'll find a lot of info. Your pretty new here so maybe he thought you didn't know. Since it was posted several times the search should have showed you several threads. The problem is the search has to be pretty exact. And since the A518 is also called a 46rh or 46re they might have been under that title. And 74 Dusted is right about the bolt pattern. Nothing like a small block so it won't bolt up. An A518 from a gas engine will bolt up but you need to do some cutting to make it fit.
