A: We have a decent engine builder at my NAPA store with some AMC experience. If I take them the core, they build it for @$1500 (depending on cam choice, etc) and stand behind it. 90% of the shops with a reman 401 need your core to do so. (or the core charge is a heavy @$500 or so) To run a 401 where the 360 was, you need the correct harmonic balancer and flexplate or have the engine balanced to zero and run the 6 cyl flexplate (personally prefferable because less vibration means longer life and easier to get parts for down the road) From: <eagle@xxxxxxxxxxx> To: mail@xxxxxxxxxxxx Subject: Used and rebuilt engine info Date: Fri, 15 Apr 2005 10:13:32 -0400 http://www.actionsalvage.com/engineschrysler.asp Just searched for web prices on rebuilt engines for my Ambassador and GW. Found this site and there was a lot of engine info on there. Old news for most. See below. (Propane 360?) Are these prices ok? Or am I better off having a local shop rebuild mine? Money is tight so top of the line is out for now. Also there is a rebuilt 401 available on another site. Can I put that in my 89 GW? Or even the 70 Ambassador SST? The ambassador is a long shot. My car is 2 barrel but there was a 4 barrel option available. I am sure there is a lot to do to get that to work. Thanks, Rick
