Lets do a little bench racing...

Rear gears are 3.23. The cam I'm not sure about, it was in the engine when I got it. I have no idea on a transmixer, so odds are its whatever was stock with this 727.

Here is the link to your cam card. Make sure you bookmark this or something, likely you'll want it later.

I'm gonna go with high 14s/low 15s. The cam/intake/gearing/converter combo doesn't sound like its going to work well together.
