I've having trouble locating an engine stand or cradle designed for a 348 Chevy engine. Does anyone know if there is such a thing? I would prefer a cradle since I expect to be working off-and-on the engine over an extended period of time. I do have a regular rotating engine stand that worked fine for my 283, but I'm afraid the 348 may be a little heavy for that stand. Any suggestions would be much appreciated.
