Tom, I promise that the engine I had it in idled at 900rpm all day, didn't overheat in traffic, didn't surge or buck, had plenty of response down low (hey it's a blower motor, there's response everywhere) and did have a lope but not a chop. My friend Jimmy and I had a lot of time in the carb, though, and it had a strong ignition system, and big exhaust.
Qparker, with those specs I would probably go straight up or possibly 2deg advanced. It's really a discussion to have with your cam company. For the record, if you like Engle and have a good working relationship with them, you should stick with them, but the cam in my 292 has similar duration and about .100" more lift. There has been a lot of development in ramp technology that you can benefit from since Engle was doing R&D on cams. My custom ground cam direct from Comp was only 129 shipped and completed in 2 days.
