Default starting my 5.3 build...what heads??
ok, so before any of u start saying " why didnt u get a 6.0?", this short block was GIVEN to me, has less then 45k on it. FREE!!!!!!.....so now that this isue is squashed, what heads to run on it, 706,862,243,317....need some advise. im sure i will call Richard @WCCH, but for now, wanting some input. I will probably go TR220 with it, and keep all other mods in my sig. The 4.8 just isnt cuttin it anymore. I will get a converter eventually, but not at the moment. I know with this cam i will be needing one. keeping stock intake and fuel setup. gimme your input, floor is open!!!
