maybe call carter tech line to ask what the difference is for the 2 pumps? Has to be a pretty big difference if one costs almost 3x as much as the other.
Another option is the edelbrock pump, comparable or better specs that the lower price carter and it has a clockable housing that might work for a factory line? I ran that pump for a year or so and it supported ~520hp on a strict engine dyno, did 12.0-12.2 at the track with crappy old/hard tires on the cars first shake down runs.
