    I want to have more power for my daily driver. My Blazer engine is stock TBI. I bought a cam and lifter kit from Advance.(lunati part # 06103lk) I want to know if I picked the right one. The specs are: RPM 900-4800, DUR @adv-in-270-exh-270, dur @.050-in-204-exh-214, Lift @valve in-.420 exh-.442, lift @lobe in-.280 exh-.295, 112 sep, int c/l 108. I still want to pass emissions but if I need to put other stuff in the gas to pass I will. Thanks

    *Should be* a good cam for your application, but check out Crane cams website, as they list a cam pretty similar to that one I believe. Perhaps that will give you some more idea on how it will work for you.

    Thank you. I looked at the one on their website and their cam is a smaller one with a 104 lobe seperation. I also called up lunati and they told me that they haven't had any complaints about the cam. According to them, I don't need any mods. Thank you for your help. I hope this cam is a good one. I am replacing my valve seals along with a complete gasket change( due to water leaking from the back driver side corner, no white smoke or blowby). So hopefully everything goes very well.

    I've got a crane cams 204/214, with similar lift specs, on a 112* LSA, so I know they make one. However, mine is a roller, so perhaps they don't make one like that in flat tappet style.

    Engine isn't running yet, and with all the other mods, I'm only going to be able to comment on the overall performance I guess, not how much better this cam was than what was in there.

    Well I replaced the cam and valve seals. No more smoke. I gained 2 mpg in the city (not babing it) and some more power. Don't know highway yet. Still dribbles antifreeze though. I think now it is a bad freeze plug.
