That price will drop quit a bit if you install it on a small block B body because the A-518 only fits a small block application. The expense is in the machining of the A-518 case and a donor big block 727 to adapt the 518 to fit a big block B body. Hope this is clear & helps.

You only need one to skydive twice. -------Original Message------- From: Joey Date: 2/26/2009 2:21:23 PM To: 1962to1965mopars@xxxxxxxxxx Subject: Re: Overdrive transmission for our big blocks seems pretty pricey, I purchased an A-518 from a local yard for $350 and went through it for about $150, I think the guy who bought it told me purchased an adapter from JW's in Florida, seems to me the whole deal could be done for a bunch less, maybe Don Dulmage will weigh in here, he might have done this already. The A-518 is nothing more than a 727 whereas an A- 500 is pretty much a 904, pretty straight forward to rebuild with the exception of the overdrive and if it isn't broke then don't fix it.
