I can tell you this much. The engine side has a inset machined into it to fit over the outer edge of the crankshaft flange for centering the flywheel. The 327 flywheel I have is the same way. I'm going to have to do some measuring to mod a 4.0L flywheel to work on my 290 so I can bolt up the AX-15 I have to it and use a 4.0L starter too. Fortunately I know about the offsets for the starter and flywheel teeth already. I thought about using a 4.0L flywheel instead with a Ford style starter (the 3/8" offset further back of the ring gear could be used to make the instep on the back of the flywheel so it aligns to the Ford style starter, but I don't care for them) Jim Blair, Lynnwood, WA '87 Comanche, '83 Jeep J10, '84 Jeep J10 From: Frank Swygert <farna@xxxxxxx> To: AMC List <amc-list@xxxxxxxxxxxx> Subject: [AMC-list] Identify 290 flywheel (not flexplate) Message-ID: <4DE0EBA4.8060807@xxxxxxx> Content-Type: text/plain; charset="iso-8859-1"; Format="flowed" I received a question I can't answer! I don't recall how to visually identify a 290 flywheel with no numbers on it. Can anyone help out here? ------------------- Would the 290 flywheel have a square weight on the flywheel like the 390 and 360,or does it just have holes drilled in it to balance? Also is one side smooth other than the clutch surface? I think I found one, but want to be sure.
