99% of my cams are on a 111* lobe sep. They drive great and seem to make pretty good power. As per conventional wisdom, when I lay the lobe sep back it makes power later.
I would also caution on cams relying on retarding them up top to make power. The cam phaser in the LT's sucks. Aftermarket spring pressures over come the spring in the phaser and it will lose control quickly. That is why the big manufactures are now making 4*, 2*, 0* limiters. I have gone to the, lock it out, mind frame and get your valve events correct.
