Difference between 351 and 351 H.O.

What are the major differences between the two? Heads? Crank? Cam?

I think the 351w HO was one of the few engines Ford made in the 80's with a 4bbl carb. The 2nd year and later of the HO mustang engine had a 4bbl, and the 460's had 4bbl carbs.

The H.O. motor's main difference is the 4 barrel, some people say that there is a different cam (I don't think so). The motor came from the factory with 210 horse and 310 ft. lb torque I believe only like 20 horse more then the F.I. 302. It is a good motor none the less but not really anything special to my knowledge carb is the only difference.
