hey guys I have a 4.8 that I put a edelbrock 600 on and ran last summer I could tell it was running rich and tried everything except for changing the jets it ran good just could smell unburnt gas so anyways I want to jet it down but have no idea what size to go with now before you tell me this winter I put the gm hot cam in 219/228 .525 112 lsa and put a little hotter plug in so should I wait and see or rejett thanks guys

 

do you have an Edelbrock needle, spring and jet kit? Mine came with a wide range of sizes and worked pretty well in getting the car to run at the A:F ratio I wanted throughout the RPM band.

 

thanks for the info ,I do not have a kit but I am looking for one now
