lower lift with TIGHTER LSA is your friend with the weight we all have and if you degree the cam it brings the torque on even earlier......
but it seems you are already leaning that way.......lower duration with larger lift increases the cylinder pressures and the DYNAMIC COMPRESSION is what gives you torque and with the L92's the heads flow TOO fast with that MONSTER intake runner, the trick is getting the head velocity to SLOW and build dynamic compression to build torque.....make sure you talk to as many cam ENGINEER/BUILDERS as possible to get the right cam combo for the L92 but not on the head but the head installed with the HUGE WEIGHT......
gm used a reverse split to SLOW DOWN head velocity and increase dynamic compression, which works but it is crap for anything after about 5500 rpm's......
my bride has an '08 escalade and it is just rediculous off idle but dies at 5000, just falls off COMPLETELY...the factory shift point are like 5500 rpms....and it is all centered around that reverse split....
