The numbers are right. It was through a cutout right after the stock ypipe, cats and manifolds.

Here's the dyno graph.

Its interesting that the torque peak moved up about 1000 rpms. How do the very low rpms feel (1000 - 2000)?

How many rpms are you planning on spinning that thing? It looks like it will pull pretty well to the mid 6Ks.

Time for a set of headers.

Hey Tex, How much did your peak move up with the Ls6 cam?

My peak did move up, but my dyno doesn't show the lower rpms. Peak HP looks to be in the 5700 rpms area. I cant tell where peak torque was because its so flat. The LS6s large split and 116 LSA really stretched out the curves.

So......does does this look like a cam for a 5800+ lb truck, daily driven and tows 5000+ lbs every other weekend!

It feels like it did before the cam swap from 1000rpm to 4200rpm....after that it comes on real strong. It could really use a little higher idle and a 6500 rev limiter and 6400 shiftpoints.

I don't think it would be a good cam for big truck.

Do you have any suggestions of what would be?

A 2002 Ls6 cam or a smaller comp traditional split.

We ended up with 322rwhp and 313rwtq last night after playing with the MAFT.

1BADHD - How about a custom comp cam 208 212 114LSA .554 .558 +4 advance. Should move the peak down and with 10 degrees less total duration, the low end should be good.
