Well, yes and no- the 360 never really achieved "legendary" status in the Mopar world, but there were performance versions available that were actually pretty decent. The E58 (cop) and EH1 (LRT) used a lot of the 340's upgrades, but lacked the 340's higher compression. Still, they were no slouch.
And a case can be made for the '88-'92 360- The LA roller motor. Yes, a truck motor and not a "performance" engine per se; it was handicapped by the early attempt at a TBI system and a rather blase cam, but every one of these I've had apart used windage trays and decent flowing (308) heads among other HD parts, making them an excellent basis for an LA build.
