If ya knew what you were talking about there, that would be cool lol. A LSx isnt ANY cheaper upon initial purchase than a seasoned Windsor motor, nor are they easier to get. Both are about the same avail wise. A 351W is a 2V pushrod motor just like the LSx, so it has the same parts. They also are damn near the same weight.
So the Ford doesnt make a good N/A motor is null and void. Have you ever priced a good set of LSx heads? BIG $$$. LSx’s arent as “cheap” as everyone seems to think.
