They used 4bbl Motorcrafts too.
It's hard to tell from the original post, but it sounds like cornejocalpoly may be choosing between a 4bbl Edelbrock, & a 4bbl Motorcraft.
I think the designations for the 4bbl versions are 4300, and 4350 (it's been a long time since I messed with one).
The 4300 is a square patturn 4bbl, that should interchange with your Edelbrock (Carter style) carb.
The 4350 (my 77' 401 had one), is a spread bore carb, and won't interchange with a square bore intake.
It's easy to figure out which one you have, the square bore has 4 equal sized throttle bores.
The spread bore has 2 small primaries, and 2 large secondaries (though not as dramatically different as a Q-jet carb).
These carbs are similar to the 2bbl versions, but I don't know if they work as well off road as the 2bbl Motorcrafts are know to.
