I've got a 65 galaxie 500 xl with 390 engine I am restoring. My dad has had it parked since the 70s so I know nothing has been changed since then. I was tring to find out if it has the original motor, which would be great I was hoping to have all numbers matching. The date code on the car is 30A26, the Block is C4AE 6015-A, the heads is C4AE 6090G. I was told it came with the 390 thunderbird engine and it does have the chrome thunderbird valve covers. Any help would be greatly appreciated. Thanks.
