    using the compression calculator and 78cc for TF240 heads putting the other parameters in>4.350 borex3.75, .039 h/gskt etc.>
    KB pistons would yield 10.86:1CR with 0 deck
    Spreed Pro would be 10.66:1 with 0 deck
    depends on your block deck height etc.
    not an expert on this, perhaps others here can chime in if I've got it wrong.

      Might want to look into Hughs Whiplash cam. They are made for a low comp motor. I have one that has maybe 100 miles on it. Ran it in my 78 440 until the bottom of the oil pan met the top of a man hole cover less than a block from my house. I got the OK from the wife to "fix it right" so I'm putting a stroker kit in this time. I loved the sound and it ran great. Get on it just a bit and you're spinning the tires. Would be willing to part with the cam and lifter (marked for where they go on the cam) as I don't have any other compete 440s that I would do another low comp build with.
