Block has been zero decked. The machinist said they took almost .030 off. That is more than I thought it would be, when I added up the numbers.. something is off.

L2355F compression height is 2.061
Stock 440 rod length is 6.768
half stock stroke is 1.875

Total height= 2.061 + 6.768 + 1.875 = 10.704
440 Deck height is 10.725

So, the pistons should already be .021 in the hole..

Then I found the issue. The 440 Source stock replacement rods are not stock length. They are 6.76, not 6.768. Unless Im mistaken, they are shorter than a stock 440 rod by .008"

Now it makes sense, as my pistons were actually .029 in the hole
