ThanX (techinspector1) for your insite and giveing me a better understanding about cam's, i do infact understand something's about lift, duration, and overlap, it's just that i havent had a chance yet to here what my cam sound's like. My engine's still on the engine stand with the cam dialed in and stuff soon to be fired up. I guess what i wanted was an oppinion about the Comp 268H. It would be nice if there were some sound bite's with each cam so you could here what it sounded like before you bought it. Since this is my first build and im just about finished with it, i did'nt want to wait untill the engine's all together just to find out that the cam choise that i made was wrong just to tare it all down again.
