Why in the world hasn't there been anyone coming out with a SW7, SW9, SW1500 etc. engine? It seems like it would fill a huge void and they were used everywhere! Seems like there has been the NW-2 and the MP-15 but that is it. Seems like a great next project for FVM! Also, I have a couple old Life Like SW9's and while I really like them they will not run on the code 55 I am using. Anyone out there know of a wheel swap for them? Or if not what are the options for getting them to run on code 55?
