Hey guys, im working on swapping a 5.3l (LM7) into my Mazda Rx8. Im planning on putting 243 heads (with yellow ls6 springs) on it, an ls6 intake (maybe a fast 90 if money is there), and a cam. Ive searched around about a cam for a 5.3 with similar heads/intake combo, but every cam i have seen in build threads is different haha. I was thinking maybe a 228r (228/228 .588/.588 114lsa) cam. Would this be good with these heads and intake, bad? Just wondering because i want to find out on here before i buy a cam then end up exchanging it. Any info would help thanks guys.
