Both these cams are pretty high lift and probably have more radical idles and will require a stall convertor. Even the ford racing cam e303 grind require a stall. I would suggest either 3.55's or even 3.73's and a aod tranny as the gears and overdrive will provide a better drive. street car or not with a c4 and 3.25's she'll be a pooch of the line.

Good luck,
