Kind of funny story...I was at a shop this week talking to a guy that is heavily into cars. He has a 1973 corvette with a 650 hp EFI big block Chevy engine in it with a Richmond 5 speed and 3.73 gears.

Last year, he wanted to go a little faster, so they took out the solid lifter cam and put a roller in it. The cam they put in was pretty radical from what he said. They took it for a ride and both were amazed at the new found power. He took it to his buddy's shop and threw it on a dyno to fine tune it. They ran it and found out it had 100 LESS horsepower than before! The old man that used to own the shop (he retired and gave it to his son) came over and said #3 spark plug was arcing. Lo' and behold, he was right. They fixed the wire and added 150 hp (50 over what it originally was).

Sometimes a lot of sound and cool parts do not equate to actual horsepower. He was laughing when he told me this story but he swears that the car FELT like it had tons more power after the new cam was installed all the way up till they saw the numbers on the dyno. The dyno stated different.
