what do 351's like

82 GT · 03-26-2002, 10:32 PM

It's pretty much well know by now what the 5.0 and 4.6 engines like in terms of adding horsepower to them but there doesn't really seem to be too much documentation about what 351's like in order to add horsepower to them.
We have seen tons of different dyno tests on the 5.0 and 4.6 engines over the years but not much on 351's
I realize that a 351 hasn't been offered in a regular production mustang since 1973 but is that good reason not to explore its possible HP potential?
I also know that the 5.4 has prety much taken the place of the 351 just as the 4.6 replaced the 5.0 but there are still some stangers out there that build 351's and put them in mustangs.
I just thought it would be nice if we has as much information on the 351 as we do the 5.0 and 4.6

The 351 and 302 are extremely similar. Just take what the 302 likes and go 1 step more radical is pretty much your answer. There are tons of 351 combo's on the board right now.

The 351 has the advantage of having a significantly stronger block than the 302 so you can utilize the additional displacement, too.

From my understanding a 351 is basically the same as a 302 except it is taller and a little wider. That is why 302 heads work on 351's or vice versa but 351 intakes are different. My dad is building a 351 - 383 stroker for his mustang but that is a while off lol
