It’s basically a step up from the 284/484 and a step down from the 292/509. The Mopar Performance engine book mentions that cam in an example of: changing cams after making some other drivetrain changes, and upping the cam to take advantage of those upgrades, such as a converter. One wants a little more than the current 284/484 but feels the 292/509 is too big for the combo. Bring in the 288/497.
And speaking of converters, you could really use a much higher stall than that 2500, like a 3500. Get right up to the rpm’s where the power comes on as you mention when you hammer it.
