Hi!
I will put a 4-bbl Holley 600cfm DP 4150 with mech. secundaries with a Engine intake (kind of/similar to Clifford)into my Chevy 250 and was told that I should use Percy's Adjust-a-jet to eliminate the "guess-work".
Yes, I don't know how many times I'll have to open it and change its jets. And yes again, I'll have to buy a jet kit if I want to try some different packs.
So, here it goes! My question is: has someone used a Percy's adjust-a-jet before? Does it really works? Or quick-change fuel bowls is the best shot indeed?
I'm not worried about it's price at all, just worried about if it's easier to tune up my engine. To open the carb and disconnect the fuel line many times, for example, isn't good for the carb health. And so for mine.
I have an operating Oxygen Sensor in my car and it will help me a lot in this battle!
Thanks again, guys!
