WarEagle1 - Your 292 requires a different passenger side mount support on the frame than the original 230/250 mount you have pictured. It can't just be moved forward like you mentioned. The upper section of the mount (the parts that bolt to the engine itself) is also different than the 230/250, plus there are some bolt spacers needed for attaching the right side upper section to the block mount location. The good news is the holes for the correct 292 support are all there in your frame/cross member so no drilling required. You just have to have the right support. I've attached a couple of pictures (for reference) I snagged form various on-line conversations about the predicament to try and help with answering your question. There are also a few existing threads on your topic in Stovebolt. Just use the Search page to find posts related to "292 engine mounts". If you need to go on the hunt for the correct support and related parts, don't forget you can post an ad in the Truck Parts Wanted forum. smile
