Description
AMC AMX Javelin late 1969, early 1970 390 core block. Standard bore. Mags good, std now and will clean at .010, you may get away with a ridge ream and hone, but I would not. I would have custom pistons made at .010 over. You just don’t find them like this any more. This was out of a 1970 Mark Donohue Javelin.
