Keith, the very best way to check engine size is to get your hands greasy! Feel along the side of the block just under the engine mount plate. The displacement is cast into the block in raised numbers. Make SURE you feel for all -- the "6" in 360 feels an awful lot like a "0" (as in "401") when you aren't careful! There's a very slim chance that there are no letters. That would be a rather rare service replacement block, and could be anywhere from 343-401 depending on bore and internal parts. As I said, those are extremely rare and very unlikely! Another rare occurrence is someone knowing about the size and intentionally grinding the numbers off to hide it. That's rarer than the SR block, thankfully! You should check the VIN to see if the car has the correct size and year engine. See http://www.amcyclopedia.org/node/52 for engine and VIN decoding. The Engine Day Build Code is on a tag on the front of the right (passenger side) valve cover (if stock covers are on). If not there check the left side rear -- the covers interchange side to side. You STILL need to check the side of the block! The valve covers fit every 67-91 AMC V-8 made, so the engine could be a different size and have the original valve covers on it. A different size and/or newer engine with the original valve cover is rather common. It's not done necessarily to be deceitful, just make the car look more original. Most AMC sellers will tell buyers if the engine has been changed. And let's face it -- these are 30+ year old cars -- it's not uncommon that the engine has been replaced at some point. --------------- Date: Fri, 31 Aug 2007 15:28:54 -0500 From: Keith Evenson <epd@xxxxxxxxxxxx> I just looked at a 68 AMX to buy it is a 390 car but there is no emblem on the side that says what size the engine is. I looked on a few sites but I can not find any info on where the badging ect. should be. On some of the car pictures I have seen them on the front fender or the back fender. I have a 70 Jav and it is on the front fender on that one. Any help would be great.
