Camshaft for 4.6 with California E.O. Approval:

Recommended Posts

Don't get something that idles too rough and you should be ok. Basically you don't want the smog tech to notice. And I think you have to watch the LSA and overlap. Those two can cause issues with part throttle emissions I believe.

I have always designed our own camshafts....started doing it under Dad's guidance on Flathead Fords. Ultradyne in Olive Branch Mississippi does all our cams, so we have a couple of 4.6 grinds cooked up that should pass scrutiny...

I would just like to have the E.O. sticker...
