A cam and those heads could make you anywhere from 370 rwhp to 440 rwhp. The bigger the cam, if properly selected, the more hp and the worse driveability. The "classic" cam for a setup like that is a 224/228 XE-R with a 114 LSA and a 110 ICL (or "+4"). That cam will make over 400, and with the proper tune will still drive nice, have good low end (although not, perhaps, low-low end), and get good mileage. It will have some lope. If you want something with better driveability, go down 4 degrees to a 220/224/114/110. For more top end, go up 4 degrees to a 228/232/114/110. If, within one of those, you'll trade a rougher idle for more low end, a slightly higher peak number, and a slightly narrower powerband, go to a 112 or even a 110 LSA.

All this assumes a M6 transmission and 3.42 gears. If you have an automatic, you almost have to go to a high-stall torque converter at the same time as you go to a cam, unless it is an extremely mild cam, and the cam and converter should be selected and installed together.

By all means, talk to Greg and have him order up a cam for your specific needs. He will grill you on questions like where you want the idle, how rough an idle, how much lope, where you want the powerband, how you normally drive, future mod plans, etc., etc. The desired rwhp is almost not even a factor. We all want as much power as we can get *within the other parameters we're willing to live with*, and those are what drive the cam selection. RWHP is just a number on a piece of paper, you can't drive it.
