My small block Malibu came from the factory with bolts in steering flange 3/8" fuel line, gauges with tach, F41 suspension with disc brakes, long story short no build sheet you got nothing unless the serial on block matches the vin. So if you have a NOM car with no build sheet all you have for sure is a 70 chevelle made by Chevrolet. Keep in mind that build sheet and the block stamp can be faked.
