is this a 904 or 727

Hey Rani, are you going to make a 4 speed B body wagon? Very cool! I wouldn't rule out an overdrive 4 speed unit. The low 3.09 first will get it up and going good, and the overdrive 4th will help out economy on the highway. Plus you can find them for cheap. Neat project. Right up there in the coolness factor with 4 speed C bodies.

Here is a pic of one of my previous cars - 68 Sport Fury ragtop 383 4 speed. Sadly I no longer have pics of my other one - a 67 Sport Fury fastop 383 4 speed,
