What Do You Think Of these GM Performance Parts (Cams) for the Ecotec 4

Hey Tom,,

I think Dave at DDMWorks has been playing with those cams ando some others. I think they make good power on the NA engines. But on the supercharged and turbo engines I dont believe they very well. I think they run in the supercharged engine but they cause other issue. Like poor cranking and bad idle. Dave is on him way to Texas right now but I bet he will chime in and let us know as soon as he has a spare minute

Those cams are for the Gen 1 Ecotec engines (L61 2.2L,LSJ 2.0L) without VVT. They will not work in the VVT heads of the LE5/LE9. We have swapped over to the L61 cylinder heads on a couple builds and used them on an LE5 block before, but you lose the Cam position sensor on the cylinder head and starting the engine takes a little while longer and you lose the VVT funtionality also.

Let me know if you have any other questions about them,
Dave

ZZP cams available for the LE5. Very suttle differences with heads but an LE5 head drops right on the LE9 block and there are lots of LE5 head configurations available to play with.

They are not always in stock
