I agree with Mr P Body on needing alot of torque with the glide and running 1/8 mile mostly but I don't know if I can mill that 318 deck down to 9.525 without it getting kinda thin from what I have been told the 318 blocks start at 9.578 so it would be taking 53 thousands off versus stock or 29 more than it is now.
I also like Randy's idea on the 427 because if I leave the deck like it is now it will have more compression also will have a rod ratio just below 1.53 the 440 would have a rod ratio just below 1.46 so the smaller engine would have more compression and better rod ratio unless I deck it more as Mr P Body suggested.
