Quote: ...a good Holley 650-700 dbl pumper is worth at least .2 in the qtr
I wouldn't run a DP on a car with a little gear and virtually no stall.
Pedro, your vacuum secondary Holley should bolt up fine not sure how low it will be.
I had a 800 DP on my nearly stock 440, cast iron intake, 3.23 gear and factory converter. Ran great. In fact I've never removed the carb from the intake and will and have let others borrow it. Those that have used it feel the same and usually ask to buy it.
