I used a hacksaw to get mine off but, of course, I destroyed it. I couldn't figure out how to get that puppy off or even move it. I guess I'd try to weld a machined piece on to it that a puller would grip although you might distort it. The LS2/7 pump does give you more clearance in front of the engine. I ended up using a Meziere remote water pump which has worked really well so far, i.e. 6 months and 3000 miles of daily driving.
