Xtreme 4x4 Comp Cam

I am fixing to go thru the old valvetrain and freshen up. Thinking of going with CompCams Xtreme energy 268. Specs are .477in and .480ex with 268/280 dur. I will be replacing the springs to match along with valve job. Maybe 1.6 ratio roller rockers and chrome moly pushrods also. My truck is a 78' chevy 4-speed, 350 bored .030 over, performer intake and carb, new headers and flowmasters, and accel supercoil. I have 36x12.50 swampers with 3.08 gears in an open 10-bolt soon to get an Eaton limited slip. I am not looking for stumppulling low-end torque, I like to get the tires spinning and stay on top of the mud. It isn't my primary truck, 94 Z71, but it is so fun to drive I usually drive it to work. Will this cam cause a problem for me, should I expect to not have valve to piston clearance w/flat-top pistons? Hopefully it will give my exhaust a little rumble, rumble. Anyone who has ran this cam or has any suggestions would be appreciated

<font color=purple>You shouldn't have clearance problems (SHOULDN'T) with the 1.5 rockers, but 1.6's will increase your lift. May or may not be a problem. I'm running 10.2:1 flattops with .488/.510 lift & mine weren't a problem, but I've still got the 1.5 rockers.</font color=purple>
