Just a 284-484?

I’m sure we’re splitting hairs but how does the P4529959 cam compare to the 484/284 and the 509 cam.
It’s 497/288 on a 108 centerline.

I am running that cam now in my 360 with ported heads (around 250 at 500), Hughes 2500 stall, 3.23 gears in a ‘67 notchback barracuda. My opinion is the car comes on strong at 3500 and pulls to 6500. Sounds great at a stoplight.

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.
