Funny thing about cams. I talked to a custom cam shop and gave them complete details of my engine and car. He told me that the XE 274 was a perfect cam for my combo he said he could grind me a cam and move my torque / HP curve around but there would not be much more hp to make. My buddy's who uncle is the cam guy said it was wierd for him to say i had the best cam because he always wants to improve engine combo's for guys. He says i really must ahve a good cam for the heads i had. mid you then i had the holley systemax II heads.
