I have learned something that might keep me from using the 292 after all. The GM parts book lists the flywheel for a 292 different from all other engines. I thought that they used the same common flywheel/ flexplate as a v8, like a 230-250 six. The catalog does list a 292 automatic trans flywheel , so they do exist, but I have never seen a 292 with an automatic,so they might be rare. Anybody know what the difference is? Something that can be changed , like drilling out bolt holes? Thanks.
