Now yer talkin! I am a fan of the 427 from way back. I don't know about the 4:56 gear though. I ran that ratio in the Nomad for a couple of years. The first 1/4 mile driving was fun, but that got old quick. I ended up with a complete Moser with 4:10 ratio.

I'll deal with the gears, I have a late model truck with overdrive and cruise control when I want to go long distance. I want the experience of solid lifters and steep gears.
