agree with others that you are probably pushing thru your converter.....a tight converter may cause you to lose some 60...depending on motor........could just be too much gear and converter combined for motor charictaristics....

[email protected] A little higher than I wanted. I was told I had enough compression to run the cam and it should pull to 6k with my heads. Only running it at the track as its a heat score on the street.
But this brings up another question after I did some reading. I'm running 660 center squirters. They do not come with a power valve and and apparently it is recommended to only change the jet up or down 1 size. Running 72s. From what I read without a pw Holleys tend run rich at top end. Fact or fiction??
