Since 1970 Pullies are different size than 1971 has anyone ever dynoed them? And how about March Pullies? They claim a HP gain if you run them. Anyone ever dyno them to see? Thanks in advance for any tips .
Be Careful About Running A Larger Water Pump Pulley On A Street Car. I Don't Know If The March Kit Offers This But A Larger Pulley Will Run Slower And Could Lead To Overheating. Good Luck
I actually have a full 1971 Pulley Setup and a March Pulley Setup so at this time I could use either or. I'm leaning towards the Factory ones but would still like to know if anyone tried them and saw a HP gain?
