02-04 LS6 cam with 112 Lobe Separation
I read an article recently (Hot Rod Mag 4/05) about modding the LS2. In this article, an 02-04 LS6 cam ground with a lobe separation reduced from the stock 117.5 to 112 (I/E duration and lift were identical to the standard LS6 cam) was dyno tested in an otherwise stock LS2. This cam produced very significant power gains at the flywheel over the LS6 cam in the LS2, i.e., 39 peak hp, 29 avg hp from 2000-6400rpm, 50 peak tq, and 36 avg tq from 2000-6400 rpm. The 01 LS6 cam (used as OE in the LS2) produce similar results (slightly less power due to less lift and duration of the 01 cam) with a similar reduced lobe separation. According to the article, the only downside to these cams may be that they have increased emissions. Otherwise, the engine operates like a stocker.
Has anybody tried a cam like this in their C5Z?
