Long and short of it, the head gasket let go back in Feburary. New head, gasket, ATS manifold, ARP head sutds, etc. That lasted 7 weeks and the 53 block cracked. At the same time I sent my ATS back for a rusting issue. I told them I needed it no later than today and would pay extra for the quicker shipping. They had all my contact numbers and still shipped it ground. It will not show up until Monday and the engine goes in Saturday. What a pain in the :butt:.
