Another 703 supporter. The 702 isn't even all that lumpy in my 350. The 703 in my 400 has just enough attitude without getting rude and unmanageable.
I assume you have a BOP 10 bolt? That would mean a series 3 carrier for your current 4.11's, so 3.36 or 3.55 would be a better choice if you want to stick with the same posi carrier. To go smaller, you'd have to get a new posi carrier, and then your options become limited.
Change the cam, make sure your valve springs are matched and/or get new ones, and get into a 3.36 gear. 3.36 won't be an ideal highway gear, but it will be a considerable improvement.
The intake change to the RPM would be better suited to your new combo.
