GPI SS4NFC cam for LS3? I'm putting a ls3 in a 69 Camaro and looking for a pretty aggressive cam to put in it and I'm looking at gpi's ss4nfc cam. I was also thinking about going ahead and get the heads CNC ported but im worried about clearance with this cam because they mill the heads to minimum to get them flat. Would getting the stock LS3 heads ported be worth the hassle? Figure i would do all i could once before the motor goes in. Anybody have clearance issues with this cam or does anybody have any other recommendations on another cam that makes the same power? Thanks

It's got a 406 gen 1 small block in it now. Needs a new carb or some type of fuel injection. Decisions decisions
A good running '69 Camaro is ****...

They don't have to mill the heads much at all to get them flat. Not sure where you're going with that. Also, they sink the valves in the heads when doing a valve job. That increases the PTV clearance all else being equal. I would get GPI's thoughts on this. Also, consider their ported and rod modded intake manifold for your build. You don't need a monster cam if the heads and intake manifold are really good. Bump the compression ratio up with a thinner head gasket and minimal head milling. Don't know what your power goals are, but my LS3 with CNC ported heads, GPI ported and rod modded intake mani, heads milled .010, .040 head gaskets, and a few other minor mods made 500 at the wheels with a baby cam. I'm thinking about putting something just like that in my '69 Camaro.

The old 230/236 112+4 cam from Spinmonster is proven 500whp with supporting bolt ons. I have a new Summit 8710R1 I would sell, 230/242 113+4 .620/.600. That is a proven 489whp cam with good torque everywhere. Out powers some cams bigger than itself.
