My friend has a 94 v6 mustang and he says he is going to put 10 thousandths of an inch longer pushrods on his intake valves and 5 thousandths of an inch longer on his exhaust valves. He says he is doing this to get a lopey sound and some power. He also said he is going to use pushrods from a 302. Is this worth it, is it going to give him any noticable lope or power. I was just wondering because it dosent sound like it will work or be worth it? Will it?
