No offense or disrespect intended, but you are showing your inexperience or lack of knowledge with your statement about Ford parts as it relates to differentials. The Ford 9" has become the differential of choice for many, many street rods, muscle cars and off-road vehicles pushing power far exceeding what you'll ever get from your little 327. You'll find a wide range of folks here, some partial to the bowtie, some to the blue oval, and some to Mopar and we all get along quite well, generally.

Good luck with your build.
