hey guys i have a carbourator question. i have a chevy 350, with a edelbrock performer rpm intake, a holly street avenger carb 570 cfm, headman hedders. i had just put the intake on and noticed a loss of acceleration and overall performance. i had a edelbrock eps intake on before. the new one is about an inch taller. it seems to be dumping a lot of gas and not burning it all. Could i need to change jets? i live up north and the elevation in around 640 meters above sea. do holly carbs crap out easy??
