what do 351's like

[82 GT]

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
