Idle is always a part of the puzzle.
I have a 486hp 460 crate with aluminum.
A friend has the 535hp 460 crate with steel.
These two cars idle exactly the same. I think it is the flywheels leveling the playing field. Just a guess.

ps..the aluminum is holding up fine after alot of abuse. I have a backup flywheel, clutch and pressure plate waiting for the day. This way I don't have to worry about how long it takes to get the old parts serviced.
