I think the Ford 351 Windsor had that 4/7 and 3/2 firing order also, same as the LS. Ford just labeled the cylinders different and the firing order starts with the right front bank.. Same cylinder lay out as a Pontiac with the passenger side bank to the front. So having the the passenger side cylinders out front didn’t stop Ford from doing it.
