73 dart custom 4dr 904auto 225/ 8.25 rear with 3.23 diff ratio. 9.5cr. Smoothed ports. Use will b mostly as passenger commuter on interstate in the truck lane for fuel savings.(2500rpm) Occasionally will see use transporting home improvement supplies or trips to landfill less than 100 miles round trip on flat ground. Light trailer less than 2500 gvwr on frame mounted hitch. May put an aerodynamic camper of similar or less gross weight for family trips on the trailer with possible vacations in the oregon cascades in mind.

Would it make sense to leave the cam wth the same timing interval, overlap etc but raise the lift only to the max that will affect flow with stock valves? I have seen the rv15 mentioned but it looks like a hydro cam.

Should I keep the vacuum egr for economy?

Search the site for the two RDP Erson cams we developed.
From your description, the RV10/295 should work well.

Thanks dd. I have found a lot of chatter on erson rv10 and rv15 cams. It seems some of the links to explicit numbers have gon stail. Is there somewhere I can get the numbers to have a machinest regrind my core or do I need to deal directly with erson? What is the performance comparison between the two cams?
