Haven't got mine finished yet, likely not installed till fall so the jury will be out for some time for me. For the money, the parts used and what machining processes have been performed (quite a bit) it's a deal. Mine came with an 89 LA roller block, magnum rods w/ARP bolts, KB 416 .040" pistons. I've inspected it enough and along with my experience with engines have no worries whatsoever. My thoughts? Do as much research as you can to decide.
