^^^I'm not sure, but I think the Texas Speed's 418 is derived from the LS3, as I think the stroke is still 4.000". The one I was referring to is the LQ9 build. I know for a fact that they say don't use a power adder on the LQ9 418 due to the stroke length. If you keep the stroke at 4.000", then you are safe to use a power adder.
