What gains are you looking at on a Heads/Cam Automatic? Is it even worth the switch? Anyone have a Dyno graph I can look at?

Thanks

There was a guy here who lost power with a H/C setup when he switched from the LS6 to the LSX 78 mm.

If you are going to switch, I would suggest getting the 90mm ones (if your engine can support one that big). If you have LS6 intake, I would not recommend a switch, too much money for little gain. I am looking at the LS2 intake manifold myself.

I think the dynometer forum would be a better bet to get it though.

What are the specs of the f13 cam, my memory says that cam is middle range?

(not as big as the t-rex, bigger than the LS6)

as stated, get the 90mm. the 78mm, to me at least hasnt proven worth the money over the ls6.

Cant remember the exhaust but the intake is 585/595

The 90mm should get you some nice gains over the LS6, prob like 15 with the TB. Your H/C would like it (just remember to get it retuned )

For the money though, you could probably spend it on something a lot better.
