Need more info, FishFinder. What year engines? What parts do you want to swap?<br /><br />If you are thinking of making a 200 out of your 150 with parts swapping I think it is very unlikely.<br /><br />Good luck.
I don't think so, FF.<br /><br />The engines have different stroke and different bores.<br /><br />Therefore the rods must be different lengths and the piston height (above rod journal) may also be different.<br /><br />Sorry.
