Or... You can do as some friends of mine in Lima Ohio did. The boys blew their engine the night before an Outlaw race at Eldora. They had an old station wagon with a 400 in it setting out back of their shop. They put the engine in but it suffered the same fate you are encountering. Running short on time one racer yelled to the other " Go get the wrecker Scritchey ! " They pulled the plugs out of the engine and pushed the old car around the building. The brothers stopped occasionally to put some more tension on the engine plate bolts as the hole opened up. Later that evening the ingenious machinist`s got the car qualified, won a heat race and was running up front in what was then the Fram Dash, before a couple of those stock 5.56 chevy rods decided they had enough and went on vacation out through the oil pan.
