I'm into a l33 2007 5.3 243heads with dod/afm. 30k miles. Was pulled due to stuck dod lifter tap. Will need new lifters etc and plan to put at cam in at the same time. What spec cam should I be looking at? I have enough room to run a truck intake or car. Block hugger hooker headers, TH400/3.8atlas 5.13tons 40-42" rubbers. Thanks for the help. My search of "l33" on here landed me 3 results. I know this is dang near identical to lm7 etc but with flattops and all alum.
