What car engine are you talking here, the passenger car 5.0 or the Mustang 5.0?

Unless it's the Mustang HO motor then yes... absolutely.

A stock 5.8 of this vintage would burn more gas but not deliver a lot more power, but upgrade the cam and it would be a FAR better truck motor than any 5.0.. regardless what cam it has. It will be a little harder on gas than the 5.0 around town but better on the highway simply because it won't downshift on anything but really big hills.
