I heard it was a gas gussler and the gearing is important. I'm starting from a blank frame so I'm thinking the Muncie M20 (4 speed manual) and getting a Nova rear end. I'm also reading the T5 overdrive tranny is a good choice. I'm looking to make this a nice and comfy highway driver. I do have the IFS setup for the front so that will help. Always looking for comments and advice.
