i dont always agree with mike but ryan your part choices are all over the place some expensive some cheap if you want the ls just to have a motor then do all oem and drive it till you can build a head worth building ie gsr head , itr head if your not going for boost forget about doing cams and such in a ls its pointless. Do a oem rebuild on the motor drop it in drive and be happy while you get another motor on the stand hence what i am in the process of doing
