I just bought a 69 rs z28 daytona yellow 410 rear project complete numbers matching drive train other than the block i cant see a vin .my question is I know the block is the born with to the car .but I cant see no numbers off the side of the block I see one number barley its a 6 witch my vin starts with that but that's it the block looks like its never been tampered with at all still all std .the build date is 02 D .is this normal and how bad will this hurt the value of the car when restored what would you call the motor to the car unknown ? All the dates line up perfect to the build date of the car .the owner has had it since 72 that block was in the car when he bought it.the block does have the VO225DZ. Casting date B 19 9 the heads are both dated b 20 9 what would you do if you cant see anything
