[QUOTE="Mrhorsepowerlsx, post: 3032, member: 395"] Let me see if I can answer your cam questions here. I have built a wide varity of LSx motors from cars/trucks/boats and for retro-fits from 4.8's to skies the limits sizes. Soo if I correct any ones messages on here, I mean no harm by it, I'm just trying to shed some light as this is a widely discussed topic.
