It'll go up steep grades in OD just fine . I love how smooth it idles at 600 rpm and the exhaust doesn't smell horrible and it pulls clean to 7000rpm .

good to hear! That’s what I want as well 600rpms glass idle and great vacuum for brakes. My 218/228 custom blower cam from cam motion only makes 13” in gear at 700-750rpms and it’s got alittle lope to it compared to the factory 5.3 cam. I don’t like Lopey chop chop and high idles. I bought the custom cam bc they said it would idle at 600 and make 18” of vacuum all day but that is not the case. I’ve had it apart a few times and verified cam is dot to dot and have played with the tune but not getting any better than that.
