I have had holley blue pumps give me great performance and reliability. One of my holley blue pumps was 18 years old when I decided to make it a spare and put a new one on. This was in a street car so it had lots of time on it.
... I was running 2 of them in parallel and was
running 9.40s in a 395 ci.. even two of them might have been
over kill... but I wanted to be safe.. later I was running a
pair of 140 Holleys to run 8.90s and that was over kill...
but I run a return line on all my junk so I ran a return style
regulator... and the later system was with a 1.19 60'
