Really depend's on what the end out come is that you want...

It's a V8, you can pretty much do anything to it. Start with opening up the exhaust and intake, put in a little larger cam...

Do you need to pass emissions tests?

If it has the factory 2 barrel intake and carb then those would be the very first things i would switch out. That alone will make a notable differance in performance

An 86 351 should be the HO, which will have the Motorcraft/Holley 4180 4bbl carb and a warmed-up cam. You would have more performance with something like and Edelbrock Performer intake manifold, but the difference wouldn't be large. Probably the best thing would be to change out the cam to maybe the Comp Cams XE250H. And, true dual exhaust will help some, but only if you are really winding it up.
