Re: Carbruator for best gas mileage
I looked up the 600 cfm Holley on Summit and says not to use with overdrive transmission, so if I stuck with Holley it would be the 570 street avenger. I was also told that the Q-Jet has to be tuned about every 3-4 months. Don't know if that's true, but that's what I was told by a tech.
