... several people told me the same to stay away from the hemi race pump, after going through 3 diff carter 440 pumps I installed the hemi race pump and my issues were solved. I could have saved some $$ by buying the right pump in the first place. Honestly I think most would not know that they are fuel starved on top end because they don't work their cars hard enough to find out. If you do I think the choice is clear.
