With the 6.625" rods, Racetec pistons with a 1.575" compression height and a 4" stroke crank I believe my machinist had to remove .040" to achieve a zero deck height from a virgin 400 block.
Your deck height would have to be 10.220" with a 4.21" stroke and 6.625" rods with the pistons you have. Do you have 6.625" rods? What stroke is your crank?
