ALERT!! SOUND THE ALARM!!..

I bet you have them apart for inspection before Xmas and reassembled just after New Year. lol
What are you doing with the big block mounts.
probably. LOL. Since I was in my late teens, I've always wanted a 440 (or big block Duster). I've had big blocks, but not in a Duster/Demon. Of all my A-bodies, 318's, 340's, 360's, never one with a big block. I see it happening in my future - maybe near future :) Still debating on SM heads for big block. I may pull the trigger before Monday.
