I have a large collection of parts sitting around and i was thinking it would be kind of cool to combine the styling of a 450 k0 with an inline 4 cylinder. I have 350, 400, 500, 550, and 750 engines to choose from. I think the 550 would be most ideal because its the best balance or weight and power, imo. Has anyone ever attempted to put a 4 cylinder engine in a 450? Im sure it would be easier to go the other way around. But i really like the idea of a 4 cylinder black bomber and i have a bomber frame already. Anyone have any thoughts on this?
