351 vs 351h.o. - someone educate me

What little bit I know, I learned from Havack's website . . . in '85 Ford switched to an h.o. version of the 351w, with some impressive gains in performance. What're the differences in the 'old' 351's & the 'h.o.'?? Is all that performance gain due mostly to fuel injection?

The 351w HO has an RV cam and a 4 barrel carb vs. a 2 bbl standard cam for the regular 351.

The fuel injected 351 was released in 1988.

Re: I\'m edumacated now !

well...different intake to accomodate the 4bbl carb.

I'm pretty sure the exhaust is the same. Maybe someone else can confirm that.
