I got a 847 cam in my car with stock heads (for now) and wondering what i should set my shift points for. Right now madz28 set the shift points for 6900 and im pretty sure thats too high for stock heads to flow. And it would be poitnless to rev to the moon and not make any power. Who has dynoed this cam on stock heads and where does the power start to fall off??

That sounds about right, I was shifting my gm846 (222/230) at 6500.

I have the cc306 on stock heads and ran it up to 6500 on the dyno. At 6500 the horspower was running flat and did drop until I let up on it. I know it is a different cam but I think that would be about right.

Automatic car with a big stall UN-locked. I am sure Lloyd's LE1 Combo is much better for daily driving This was one of his first setts he sent out nation wide.

That is about right for a M6 car

His car is well beyond heads and cam at this point. He must have been referring to an old setup or a customer car.

At what rpm?

I have about 3000mi on a fresh bottom end 847cam only setup, and I have been shifting the car at 6800. At 6800 the power is not falling off my anymeans.

I'd like to see the difference between a LE1/XFI230/236 combo and a LE1/GM847 combo. I loved the Gm847 in my 355.

I am impressed with the LE1 heads and those cams. It's tempting to get a set of LE3's for mine!
