Default Re: MQ Suffix Block

Got the block home today and all looks good. It is a 69 copo chevelle block 427, 425hp motor. I received picture of the original car and it was not from the east coast but rather Colorado and was completely rusted out. The casting date on the block looks to be A 15 9 and the assembly date was April 10. I will not be posting the vin on the front pad until I can do some research. The bore is standard at 4.25 with original pistons, camshaft, rods and crank. A truly great find.

Can you tell me what the correct part number should be? I was provided the original camshaft in a separate box with the the engine.

Camshaft is correct, #3863143, casting number stamped on end some were 3144, some were 3863144. I have an NOS one for sale right now.
