low compression

i like hughes stuff, ive had good luck with it. im not sold on those whiplash cams though. they have a lot of overlap and the big selling point is the sound of them, they say it sounds like a funny car. i looked into one for my 400 in the duster. im not looking to have all bark and no bite, i cant see spending the cash on one to see if its really going to do what i want. i dont care if it sounds stock, as long as it makes the power where i need it.
