Mopster,

I feel your pain my friend. I have now been through 2 blocks and now waiting for the 3rd attempt. I must admit that mine are P5153478AB 59 degree siamese finished at 4.040" and I was aiming for 4.125" bore. However, you would think for what Mopar charge for these blocks they would get it right, not to mention the fact that we have them shipped half way around the world. The first picture is the sonic report of the first two blocks I recieved and the second is of friends 48 degree low deck for comparison. At the end of the day I may just go for a smaller bore to make way for a rebuild down the track. Pitty I already have the pistons.
