Ron & Greg. . .this thread has morphed into a cam discussion, but that's fine with me. . .

. . .how would you guys compare this Edelbrock cam ( http://www.edelbrock.com/automotive/...2157&submit=go ) with the smaller Comp camshaft ( http://www.compcams.com/Company/CC/c...csid=1215&sb=2 )???

On paper they are VERY similar, but I don't have enough experience to know how much difference the small differences on paper between the two would make?

I'm looking at exhaust systems right now as well. . .at the moment I'm looking at a Magnaflow system and I have a choice of 2.5" or 3" systems. . .would selecting the 3" exhaust have a negative effect if I have a relatively stock engine (with one of the two cams above; the car already has headers on it. . .I think they are Hooker headers, but I'm not positive because they came already installed on the car and they are wrapped)? I'm just thinking that I would eventually want/need the 3" system when the engine gets modified if it wouldn't adversely affect the engine now.

Thanks again for the help!
