Keep the F303..trust me on this one. You'll suffer maybe a tad bit on the low end, but mid range and top end you'll gain. The other cams such as the xtreme energy aren't gonna be that effective on mid range and top end as the F303. Or if you want a different cam all together, change to a Comp Cams Nitrous Cam. They work all over the rpm range. Good luck!!
