Mopar in a Mustang ...

Personally, even though I've always been "pretty much Mopar" so far as musclecars go, I say leave the stang alone. If you want to bring a great Stang back alive, do the right thing and power it with Ford.

If you REALLY want'a tick off the Ferd owners, git yourself a Cobra Kit and stick an injected 5.7 / 6.1 in the thing
