a 32-3400 stall on that cam would be golden, since it doesn't do **** before 3k anyways

There is more cam out there that can get the job done without needing a 3400+ stall

Everyone is right about a minor loss of torque down low. Honestly it was not that significant of a loss. I was worried about it however, hence why I installed my 4.10's. Btw the 4.10's were probably the best $ I have spent thus far

I found an old thread by ls2portworks on the ported L92 and Cory/WCCH found that the port work likely will make a very small difference unless you have big flowing heads, big cam, and big cubic inches
