Looks good! A lot of extra work to overcome the doofus welding.

Dumb question (which I think I asked in another thread): With what looks like a single bore master cylinder, is that an auto trans or do later trucks have mechanical clutches.

The master cylinder in the picture is the standard single pot master cylinder. Starting in 64 they went to this master cylinder and a mechanical clutch.

Alaroca,

If you have not thought about this already, you might consider modifying the breather to take a dry paper element vs. the steel wool oil bath? Its super simple, just remove all the top housing with a Dremel tool type cutter, leaving the just the top lid. I did that and she still looks like an oil Bath type cleaner.

I did the 2-barrel swap to a Holley 500CFM carb, so the diameter was different, I made a foundation for the lower pan to rest on. If you need any help, ask away.
