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.
If this block was cast for racing(with them putting
in all 8 sleeves and splayed caps) I'm guessing that
they went with a thicker deck like a R block... if
so then milling that little bit wont hurt anything...
measure through a few of the coolant holes to check...
I have my stock block cut to 9.5"
They start with a stock 318 or 360 block and put in .200 thick Darton sleeves. So no, it's not an R block.
I was looking at them too but eventually decided to stick with my stock block for now.
