my 408 build

Use the search function here to research the Blueprint engines. I think at least one member had a bad experience with one, maybe more. As far as building your own engine, you know what you are capable of better than anybody else here. I prefer to build my own engine, even if it costs me more than a crate motor. That way I know exactly what was done, what components were used, etc. Also, if something goes wrong, I have a pretty good idea who's to blame.
