I have a 455 from a 1970 Olds. I tore it down, cleaned it up and painted it blue. I have all the components though one piston is in bad shape. The ID # is 396021 F, and the heads are type E with 2.00" intake valves. The VIN stamping is 30Z147096. So it's Oldsmobile division, 1970, and made in Fremont, Ca. I don't know what car it came from. The person I got it from said it came out of a 1970 Hurst Olds but I don't think they made a Hurst Olds in the 70's. Can anyone tell me what car it came out of and/or the worth of this engine?
