Adding a later flywheel to a flat-flanged 71-down crank typically requires a bushing to provide a flywheel centering mechanism, such as the brass ones made by Bulltear. I have one for my 1970 390. -Spro ----- Original Message ----- From: Jim Blair To: amc-list@xxxxxxxxxxxx Sent: Sun, 4 Oct 2009 23:18:14 +0000 (UTC) Subject: [AMC-list] Crank flange of 290 vs 4.0 vs 304 I'm looking to put an AX 15 in my 82 Honcho and Isabelle's Rebel. Anything special needed to swap a 4.0 flywheel to the 290 and 304 other than rebalance? _________________________________________________________________ Hotmail: Free, trusted and rich email service. http://clk.atdmt.com/GBL/go/171222984/direct/01/ -------------- next part -------------- An HTML attachment was scrubbed...
