most people dont think of modern 4 cylinders being very big, and most are not. mecury marine(mercrusier) took a biog block ford 460 and turned it into a 4 cylinder for some of their boat motors. they made a aluminum block, and a forged steel crank shaft and the pistons and rods and cylinder head form a 460 engine, I domnt remember what stroke it had if it was 460's stroke or more, but those motors had lotsa power& torque for a 4cylinder in a boat.and light to with the all aluminum engine block.I think they made it up into the 90's possiably into the 2000's.Ive worked on quite a few. as I recall they called it the "470" possiably for 4 cylinder and 70 cu per cylinder...
