I recently bought a McLeod 130t flywheel off summit with the little incherchangable weight package. I'm currently running an LA 360 but I would like to keep my options open to swap to any other small block in the future. Haven't installed it yet but did open the box and it looked to be excellent quality
It comes neutral balance so it'll bolt onto a 318/340/5.2. Or you can add the weights for either 360 or 5.9
