All I was wanting to know was about people's personal experiences with a 340 cam in a 318, did they notice a performance gain,what other modifications did they do if any when they went with the 340 cam? I know that the 340 cam isn't available anymore so what would be pretty close to it? I've been reading up on the Howard's cam 255* / 261* and it has been recommended by a couple of guys. Is a lunati or a comp xe grind of similar specs worth looking into? Opinions are good, but I'm looking for guys who have had personal experiences with any of these cams.
