I run one of these and it's great! It's been running now for 3 or 4 years, starts, runs smooth never overheats, pretty bombproof. I went from running an edelbrock 750, which was too rich, to a 1406 600cfm and it made a big difference--much better.
When I get some more money, I'm going to give it the Car Craft Saturday Night Slayer treatment:
