I have a 69 6 barrel road runner. I didn't care for the Holley blue pump. Im told they're okay for the track, but mine is driven mostly on the street, and sometimes at the track. I did try a Mallory 140 which I liked better than the Holley, but this one went out, but It was used when I got it. Before I purchase another Mallory, this time a new one, does anyone have any recommendations on an electric pump? Or the least amount of GPH I would need? 440, .030 over, 915's, 509 cam, factory 2100 Holleys, automatic, fuel pressure set at 7psi which I believe I should bring down to 6psi. Any help would be appreciated.
