How big of a big block (FE?). How much cam, compression, gears, etc.?

Even a 352 can use a 750 if it's running a big cam, headers, duals, lots of compression. The bigger size motors (390, 406, 410, 427, 428) can make use of a 750 because of their larger displacement even in a less aggressive configuration.

The selection between Edlebrock/Carter of Holley is pretty much 6 of one to half dozen of the other if you understand how each can be, must be tuned. The Holley is more forgiving of tuning errors, delivering acceptable performance across a wide range of needs where the Edlebrock/Carter is on or off its game, it doesn't muddle through as well as the Holley.
