Yes it is. I did google, but never saw anything that was specific to only Corvettes. I saw something about a switch from cast iron to aluminum in 63, but I thought they were always aluminum for Vettes. besides, you cant always believe what you read on the internet

Corvette Powerglides were cast iron through 1961, and changed to the new aluminum Powerglide in 1962.
