440 low compression build

-
Will go with keith black pistons as can get piston and ring kits.

Would i need step head or flat top to increase cr. Also how to i work out what size compression hight i would need

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.

Charge426 im thinking of upping the c.r so a low compression cam wouldnt be needed would it
