Thread: BIG END BUSH REPAIR . IS IT POSSIBLE ??

Block and head in one was one of the standard layouts for engines up to the 1920s, although some manufacturers had detachable heads earlier - Ford was the first to mass produce engines with detachable heads.

Very common in veteran cars but pretty well gone by mid 20's. Big side valve engines with screwed in plugs above the valves so the valves could be installed/removed.
