Now, here's something I found interesting. All the info I can find says that the 455 was available in late '75 TA's. I even found some pics of a restored 455 HO '75 TA.
Now they were HO in words only. There was absolutely nothing different in the TA engine and a 455 wagon engine. But anyhow, I wonder why the classracerinfo site doesn't show that it was indeed available in a '75 TA ?
