440 pistons

I will try to remeasure mine.
Maybe I made a mistake = I had two
23 month old Grandkids with me.

I am confused:
A 1/2 inch stroker with a 1.5 Comp. deck
would be about Zero deck with a 7.1 Rod
according to what I calculated in a 440 block.

Can someone check my math and help me out.
No, a 4.5 stroke and 1.340 cd is very close to zero deck with a 7.100 rod. A 4.25 crank and a 1.5 cd is pretty much 0 deck. I could also be wrong. Kim
