ya i have recently changed intakes from a edelbrock eps to a edelbrock perfomer rpm. right after i installed it i noticed a loss in power, i figured it was just fine tunning.but could never tune it. The motor is only 1 year old and not even 50000 km on it. my old distribtor weights were rusty and didnt spring back on there own, I needed a new distributor right from the start but didnt put one on till just the other day. it sounds good on idel but has no power when in gear, it seems to just bogg. how often do the power valves in the holly carbs go.
