What's a 1970 Corvette 454 worth?

[jasonL78]

Looking to put a value on a completely rebuilt Corvette 1970 454. 512 block, steel crank, bored 30 over. Keith black pistons and floated pins. All new valves, roller cam and roller rockers. I'm picking it up from the machine shop tomorrow. I have the corvette tach drive distributor, starter, Pressure plate, fuel pump but no 1970 intake. But have an Edelbrock RPM intake to go with it. The date on the block is K12-9. The heads are 3964290 dated L 2 9 and the other is later if I remember correctly. Be a great date coded motor for an LS5 Chevelle or Corvette.
