Well i have a cobra, and i can get a really good deal on a used edelbrock intake and ford E cam for dirt cheap. Like i think 200.00 -300.00 for both or possibly even less. edelbrock website says the performer makes 12hp over the cobra intake not sure if thats at wheels......but i was wondering if i should pick this up. Some people say the cobra intake is good for alot of power but im just wondering what should i expect if i changed only the intake on my stock car.(continue pulling harder to redline?) not looking for the opinon of those who think thats its cheap and i should get it, possibly just to resale it.
