Caidinsi if your talking about rather to check to see if your engine is ok, no warping, cracks etc. Then take it to a engine shop and have them tear it down and check it out for you. Nice work John, with a 454 bigblock Mark IV how many times would you say its ok to resurface the block? Also any info you have of the Mark IV 454, such as history or such, feel free to message me, I love to learn as much as I can, thanks John.

what do i need to do as far as getting my motor checked out to see if i even want to put money into in??
