I'm parting this 72 and I am impressed with the fit of this 455 8n this cat. Tags on the plates are from 88. Shes been sitting a long time.
They didn't put a 455 in any "Skylark" ever, from the factory. Or a 400 or 430 for that matter. The only non-GS that I know of that ever got anything but a 350 or less, was a Sport Wagon "400", thus named.
