Let me put it to you this way, once the factory got forced into the emission and Cat era and those crappy gear ratios, when you look at the 400 4bbl motors, none of them used anything larger then the 066 factory Cam!
Granted these motors I mention had less compression then you will have, but that compression gain is not enough to make up for those lazy 2.56 gears!
You have to get up to at least 3.23 gears, and 3.42 or 3.55 would be a whole lot better even if you want my 2 cents!
Also 400s love to rev, so if your putting good Rods into your build to do that don't neuter them by having to stuffing in a Cam that can barely make it to 5200 rpm and has already nosed over hp wise by 4500 rpm!
This is yet another reason for getting the rear gear ratio up!
