finally getting to the stage in my build up. it's time to pick a cam I have 400 block and it is preparing to be bored +40 I have KB flat top pistons 7cc dish 10:1 with the 76cc 441s heads block has been zero decked. I guess i'll have to run premium or race gas till i can offord aluminum heads this is the question i was thinking on going with the comp Xtreme energy 268 or 274 hydralic cam but i put off the build up long enough to have money for a roller cam my cousin switched to a roller in his 350 and he's says it's a 30-70 hp out the box his 1st cam wore out without a whole lot of use and i hear rollers last longer do to the less friction i already have 1.5 roller rockers and so on and i have to get springs and retainers either way it goes so is a roller cam worth the extra cash and what size still want it streetable
