The cranecams HR220 ( 220/220 .551/.551 112 ) has ivc point at 37.... so far this is my cam of choice, due to this. But i'm waiting on the LPE gt2-5 specs because it's cheap, and i'm thinking it'll be in the same range.

the TR 224 cam on 112 closes at 40 degrees, therefor losing some of the dynamic compression, on a motor with already lower static compression. So in my opinion... the 224 no matter on what lsa, isn't a good cam for the stock 5.3

and i'm told stock 5.3 heads stop flowing around .560 lift, so it's real close to over camming anyways.
So how does the cranecams HR220 compare to the LPE gt2-5 using 02sierraz71_5.3 cam card? Which do you think would work best in the 5.3?

the LPE gt2-5's cam card, has some weird lookin numbers on it. maybe someone who's more versed in cam card reading could help us out, me and tib's couldn't figure it out. the card says intake open 25, closed 69 at .006. These numbers aren't even close to other cams, like the TR220 for example.

unless someone feels like making a call to ligenfelter? to save 200 bucks or so......to find out the tru valve closing point.

Give me the duration, lsa, and icl and I'll list out the VEs.

Your reading valve events measured @ .006'' lift. I think you are more familar with valve events listed @ .05''.
