If it will fit/hold a big block chevy it will work fine for a 348. The 348/409 (W motor) were the precursors to the big block and the dimensions and weights are very close to the same. The motor mount and bellhousing patterns are identical. A complete W motor will weigh in the neighborhood of 650#'s so make sure your engine stand is up to it. I've got a 348 currently bolted to a universal chevy V8 engine dolly I bought from Summit on sale for about $35.00. Other than the poor import quality, and lousy casters which collasped, it does a good job of keeping it off the floor and upright, just not mobile. If you need any 348/409 info go to www.348-409.com
