Hi All, I just picked up a 455 out of a wrecked '70 riviera and I know very little about Buicks. Will a 455 fit in a '66-'67 442 without much modification? What 4-spd tranies are best to bolt up to the 455? What cars did these come in? I was considering putting it in one of my Blazers, but finding a truck trany that will bolt to the 455 would be hard, right? Now I'm thinking I will put it in a car once I find a trany and a car. Thanks. Sven
