Gents,
i am looking for your thoughts on a cam im thinking of for an 03 Corvette Z06 with LG longtubes, Corsa X, Random high flow cats, and a CAI. pretty much stock everything else and a M6 and 3:42s. its for a daily driver and i really like the idea of Patrick G's 'Torque Cam' but need a lobe i can use beehives with since its a daily and i drive 60 miles a day on it. i just want a torque beast.
im thinking of:
227/231 .614/ .617 on a 111+1 with Comp pushrods and 918 springs. or
231/235 .617/ .621 on a 111+1 with the same. both are lsl lobes.
i know everyone likes PAC, EPS, etc, but to head you off at the pass, i need to stick with Comp as they are giving me a substantial discount as i am currently deployed overseas.
i know we have some cam gurus here! any ideas on overlap, dynamic compression, etc that would make these good/ bad choices? what would be a better choice?

that would be my choice but on a 111+2 LSA (Degreed at that ICL), Usu Comp duals with these lobes or go XER and that will be 228/234 111+2 LSA (with 918s)

The 921s are a little expensive to be replacing often. I thought since the 918s are good for .625 of lift they might work with under .620.

I was going to do about the same cams that were suggested to you. Its not the lift of the lsl lobes that make it so you cannot use beehives its how aggressive the lobe is. That is why comp suggests you to use a dual spring with about 150 seat pressure. When I called up comp and spoke to a guy that actually knew what he was talking about he told me the xer lobe was the way to go with ls6 heads best performance while maintaining valve train life. He said the gains from using lsl lobes were marginal and weren't worth using on a stock head.

what differences will these two cams have with respect to valve events and dynamic compression?
again, thanks everyone for the help. over on the corvette boards, virtually no one has cams like what is popular on ls1tech. no one has anything smaller than 112+4!

It should if it is spec'ed as a "2 degrees advance" which means ICL of 109 should in theory correspond to the mark on the cam. You could always degree it to make sure the dot is in the right spot.
A lot of shelf grinds have advance built in as well, although this is not always specified.

Eveyone is always seeking the last bit of Hp out of a cam. Degreing the cam ensures it is at designed valve events once installed.
If you just going to slap it on dot to dot, I would then go 111+4 LSA. It is quite a norm to find dot to dot varying from design by few degrees.
