As long as what you're talking about is a 390 crank with 390 rods and 390 pistons, it'll all fit. 352 rods have different center to center lengths than the 390 and 390 pistons have a different pin to crown distance and skirt shape. So you can't cross breed 390 and 352 rods and pistons and get it to fit any FE block when attached to a 390 crank.
