Thinking about putting the 90 roller motor in it. Would not have to change anything. But I do have a NOS b&m truck converter I could put in it.
Knock out the freeze plugs, flush the water jackets and put new fp back in it. Check the gaskets, replace as needed and drop it in. Change intakes also to a 4 bbl. Could use the edel off the 360 that I pull out.
