1976 440 school bus engine - any good?

Got to agree with flyboy, be very wary. Before making any decisions I'd completely disassemble the engine and get the bare block (that means no core plugs or oil galley pipe plugs) hot tanked and inspected looking for crank saddle cracks etc. If everything comes out alright and you still want to race this puppy all the rotating or reciprocating parts that came out of that engine (especially the cast crank) are now paper weights. Have fun. I always have.
