It's funny you mention that. I've been kicking the idea around of building a 582 and have run about every combo I can think of through my saftware. But unless you can get a set of heads flowing upwards of 480 or so there's not much more power to be had over a 565. The 582 had just a bit more torque due to the longer stroke but hp was within 5 of the 565. So I have just about decided on a 565 unless Curtis can pull a bunch of air out of his butt with a set of conventional heads. The Edelbrock heads I've been talking to him about flow around 450 so it's close but those same heads wake up the 565 as well.
Decisions, decisions.
