Compu cams XE268H question

Huge difference between a small and big block. Big engines (such as your 440) will handle a big cam and still have good low end torque. I absolutely guarantee you without a shadow of doubt the 292/509 cam will be a turd on take off in a low compression 360 with 3.23 gears. I've seen guys do it time and time again because they don't have a clue how a cam affects an engine and pick it just because of it's nasty idle and when they get it in they aren't happy with it cause it's a dog. The 268 is much better matched to it.
